This paper presents some case study frameworks to limelight SVM classifiers as most efficient one compared to existing classifiers like Otsu, k-means and fuzzy c-means. In general, Computed Tomography (CT) and Magnetic Resonance Imaging (MR) are more dominant imaging technique for any brain lesions detection like brain tumor, Alzheimer' disease and so on. MR imaging takes a lead technically for imaging medical images due to its possession of large spatial resolution and provides better contrast for the soft tissues like white matter (WM), gray matter (GM) and cerebrospinal fluid (CSF). The usual method used for classification of lesions in brain images consists of pre-processing, feature extraction, feature reduction and classification. Early detection of the tumor region without much time lapse in computation can be achieved by using efficient SVM classifier model. Brain tumor grade classifications with the assistance of morphologically selected features are extracted and tumor classification is attained using SVM classifier. The assessment of SVM classifications are evaluated through metrics termed as sensitivity, exactness and accuracy of segmentation. These measures are then compared with existing methods to exhibit the SVM classifier as significant classifier model.

SEGMENTATION AND CLASSIFICATION OF BRAIN TUMOR CT IMAGES USING SVM WITH WEIGH...csandit
In this article a method is proposed for segmentation and classification of benign and malignant
tumor slices in brain Computed Tomography (CT) images. In this study image noises are
removed using median and wiener filter and brain tumors are segmented using Support Vector
Machine (SVM). Then a two-level discrete wavelet decomposition of tumor image is performed
and the approximation at the second level is obtained to replace the original image to be used
for texture analysis. Here, 17 features are extracted that 6 of them are selected using Student’s
t-test. Dominant gray level run length and gray level co-occurrence texture features are used for
SVM training. Malignant and benign tumors are classified using SVM with kernel width and
Weighted kernel width (WSVM) and k-Nearest Neighbors (k-NN) classifier. Classification
accuracy of classifiers are evaluated using 10 fold cross validation method. The segmentation
results are also compared with the experienced radiologist ground truth. The experimental
results show that the proposed WSVM classifier is able to achieve high classification accuracy
effectiveness as measured by sensitivity and specificity.
Comparison of Image Segmentation Algorithms for Brain Tumor DetectionIJMTST Journal
This paper deals with the implementation of Simple Algorithms for detection of size and shape of tumor in brain using MRI images. Generally, CT scan or MRI that is directed into intracranial cavity produces a complete image of brain. This image is visually examined by the physician for detection & diagnosis of brain tumor. However this method of detection resists the accurate determination of stage & size of tumor. To avoid that, this project uses computer aided method for segmentation (detection) of brain tumor by applying Fuzzy C-Means, K-Means, Gaussian Kernel and Pillar K-means algorithms. This segmentation process includes a new mechanism for clustering the elements of high-resolution images in order to improve precision and reduce computation time. The system applies FCM, Gaussian kernel and K-means clustering to the image later optimized by Pillar Algorithm. It designates the initial centroids’ positions by calculating the Euclidian distance metric between each data point and all previous centroids. Then it selects data points which have the maximum distance as new initial centroids. This algorithm distributes all initial centroids according to the maximum accumulated distance metric. In addition, it also reduces the time for analysis. At the end of the process the tumor is extracted from the MRI image and its exact position and the shape is also determined. This paper evaluates the proposed approach for Brain tumor detection by comparing with K-means, Fuzzy C means, Gaussian Kernel and manually segmented algorithms. The experimental results clarify the effectiveness of proposed approach to improve the segmentation quality in aspects of precision and computational time.

The combined Wavelet Statistical Texture feature set (WST) and Wavelet Co-occurrence Texture feature (WCT) sets are derived from normal and tumor regions. Feature selection is performed by Genetic Algorithm (GA). These optimal features are used to segment the tumor. An Probabilistic Neural Network (PNN) classifier is employed to evaluate the performance of these features and by comparing the classification results of the PNN classifier with the Feed Forward Neural Network classifier(FFNN).The results of the Probabilistic Neural Network, FFNN classifiers for the texture analysis methods are evaluated using Receiver Operating Characteristic (ROC) analysis.

Brain Image Fusion using DWT and Laplacian Pyramid Approach and Tumor Detecti...INFOGAIN PUBLICATION
Image fusion is the process of combining important information from two or more images into a single image. The resulting image will be more enhanced than any of the input pictures. The idea of combining multiple image modalities to furnish a single, more enhanced image is well established, special fusion methods have been proposed in literature. This paper is based on image fusion using laplacian pyramid and Discreet Wavelet Transform (DWT) methods. This system uses an easy and effective algorithm for multi-focus image fusion which uses fusion rules to create fused image. Subsequently, the fused image is obtained by applying inverse discreet wavelet transform. After fused image is obtained, watershed segmentation algorithm is applied to detect the tumor part in fused image.
Multimodal Medical Image Fusion Based On SVDIOSR Journals
Image fusion is a promising process in the field of medical image processing, the idea behind is to
improve the content of medical image by combining two or more multimodal medical images. In this paper a
novel fusion framework based on singular value decomposition - based image fusion algorithm is proposed.
SVD is an image adaptive transform, it transforms the matrix of the given image into product USVT
, which
allows to refactor a digital image into three matrices called tensors. The proposed algorithm picks out
informative image patches of source images to constitute the fused image by processing the divided subtensors
rather than the whole tensor and a novel sigmoid-function-like coefficient-combining scheme is applied to
construct the fused result. Experimental results show that the proposed algorithm is an alternative image fusion
approach.

Possibilistic Fuzzy C Means Algorithm For Mass classificaion In Digital Mammo...IJERA Editor
Mammography is an effective imaging modality of breast cancer abnormalities detection. Survival rate of breast cancer treatment can be increased via early detection of mammography. However detecting the mass in the early stage is a tough task for radiologist. Detection of suspicious abnormalities is a continual task. Out of thousand cases only 3 to 4 are analyzed as cancerous by a radiologist and thus abnormality may be left out. 10-30% of cancers are failed to detect by radiologist. Computer Aided Diagnosis helps the radiologists to detect abnormalities earlier than traditional procedures. Because of some negligence in capturing device, the image may be affected by noise this leads to fault diagnosis. Preprocessing can remove this unwanted noise. In this paper features such as entropy, circularity, edge detection, and correlation are extracted from the image to distinguish normal and abnormal regions of a mammogram. Classification and detection of mammogram can be done by Possibilistic Fuzzy C Means algorithm and Support Vector Machine using extracted features.

Computer Aided System for Detection and Classification of Breast CancerIJITCA Journal
Breast cancer is one of the most important causes of death among all type of cancers for grown-up and
older women, mainly in developed countries, and its rate is rising. Since the cause of this disease is not yet
known, early detection is the best way to decrease the breast cancer mortality. At present, early detection of
breast cancer is attained by means of mammography. An intelligent computer-aided diagnosis system can
be very helpful for radiologist in detecting and diagnosing cancerous cell patterns earlier and faster than
typical screening programs. This paper proposes a computer aided system for automatic detection and
classification of breast cancer in mammogram images. Intuitionistic Fuzzy C-Means clustering technique
has been used to identify the suspicious region or the Region of Interest automatically. Then, the feature
data base is designed using histogram features, Gray Level Concurrence wavelet features and wavelet
energy features. Finally, the feature database is submitted to self-adaptive resource allocation network
classifier for classification of mammogram image as normal, benign or malignant. The proposed system is
verified with 322 mammograms from the Mammographic Image Analysis Society Database. The results
show that the proposed system produces better results.
Human brain is the most complex structure where identifying the tumor like diseases are extremely challenging because differentiating the components of a brain is complex. In this paper, pillar k-means algorithm is used for segmentation of brain tumor from magnetic resonance image (MRI).Generally, the brain tumor is detected by radiologist through analysis of MR images which takes longer time. The pillar k-means algorithm’s experimental results clarify the effectiveness of our approach to improve the segmentation quality, accuracy, and computational time.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

ABSTRACT
This paper presents some case study frameworks to
limelight SVM classifiers as most efficient one
compared to existing classifiers like Otsu, k
and fuzzy c-means. In general, Computed
Tomography (CT) and Magnetic Resonance Imaging
(MR) are more dominant imaging technique for any
brain lesions detection like brain tumor, Alzheimer’s
disease and so on. MR imaging takes a lead
technically for imaging medical images due to its
possession of large spatial resolution and provides
better contrast for the soft tissues like white matter
(WM), gray matter (GM) and cerebrospinal fluid
(CSF). The usual method used for classification of
lesions in brain images consists of pre
feature extraction, feature reduction and classification.
Early detection of the tumor region without much
time lapse in computation can be achieved by using
efficient SVM classifier model. Brain tumor grade
classifications with the assistance of morphologically
selected features are extracted and tumor
classification is attained using SVM classifier. The
assessment of SVM classifications are evaluated
through metrics termed as sensitivity, exactness and
accuracy of segmentation. These measures are then
compared with existing methods to exhibit the SVM
classifier as significant classifier model.

2. LITERATURE SURVEY
Brain Tumor has been one of the alarming issue of
increasing mortality rate in the world. To detect tumor
at the earliest would be the corrective measure for
which MR Imaging is more apt for deriving the
details of the brain for acquiring significant
information.
Pre-processing of the image is performed using
normalized histogram to filter out the undesired signal
or noise from it. The second step after pre-processing
technique is various textures based and intensity
features are extracted. After extraction of the features,
the feature reduction is carried out by principal
component analysis (PCA) [2]. Finally the support
vector machines (SVM) is used to classify and
measure performance metrics like index, overlap
fractions and extra fractions. The noise is reduced
using Gaussian filter. In feature extraction, the texture
features such as skewness (which measures
asymmetricity of the data around the mean),
coarseness (based on its shape) and standard deviation
(to depict variations that exist from the expected value
or mean) are assessed to identify the abnormal cells
for tumor detection. K-NN algorithm and linear SVM
are used for classification. In this paper the
classification efficiency is attained about 94% in case
of linear SVM compared to 92% in case of K-NN.
Garima singh et. al., [4] used normalized histogram
and k-mean segmentation. Here Naive Bayes
classifies and the support vector machines are used for
classification. In this unsupervised k- means
segmentation is adopted. The centres of K clusters are
initialized. Euclidean distances between the cluster
centroids are computed. Depending on the Euclidean
measure the pixel with closest centre is assigned for
cluster. The cluster centre is recomputed. This process
is continued until it confines to one solution. Cluster
pixels are then clustered into an image. In this paper
Bayes classifier has 87.23% of classifying efficiency.
SVM classifier is 91.49% efficient classifier.

Bias correction [5] is performed on MR images by
applying Hidden Markov Random Field algorithm.
The tumor present is asymmetrical in nature hence the
intensity is also higher. Thus method includes
separation of the brain in symmetric slices and then
comparing them voxel based by subtraction method.
To extract the abnormal cell region, region growing
technique is implied with voxel having highest
intensity as seed point. Tumor shapes indicate
different stages or grades of tumor. SVM with linear
kernel exhibits much better performance compared to
other classifiers. The statistical texture and
morphological features selected is fed to different
classifiers. The maximum accuracy of classification is
achieved from SVM.
Medical image segmentation is highly influenced by
noise and the noise can be declined using low pass
filter but low pass blurs the image and degrades
edges. To avoid this degrading further median filter is
adopted which takes care of sharp edges but fine
details are lost. Thus an isotropic filter is implemented
which provide goodness of low pass filter and median
filter hence overcoming the drawbacks, Active
contour model(ACM) [6] is one of the efficient
segmentation algorithm where by growing curve , the
intended object can be separated out. Discrete wavelet
transform (DWT) is used for feature derivation, but
DWT increases the power as feature vector is tried to
reduce, Independent component analysis (ICA) is
used to reduce the vector size of the feature. The
author believes supervised methods of classification
are better in accuracy than the unsupervised method,
as SVMs can handle complex data or high
dimensional data. In this work nonlinear kernels of
SVMs are used like linear, polynomial, quadratic and
RBF etc. The result in this paper concludes that
nonlinear SVMs especially exponential form expands
the width between samples to the extent where other
kernels cannot achieve. RBFK renders best
classification accuracy compared to other nonlinear
kernels SVMs.
3. PROPOSED METHODOLOGY
SVM is more efficient as only a support vectors play a
vital role in deciding the decision boundary for
classification hence the memory usage is efficiently
used with the help of kernels, SVMs can map feature
space into a high dimension so as to represent as
collection of linearly independent set. Kernel trick is
employed based on the need to build linear model
over high dimension space.
The state-of-the-art algorithm is sequential minimal
optimizations which executed quadratic form and are
widely used.

Peronamalik diffusion
In anisotropic diffusion, it has a function to reduce
noise with inhibits smoothing at the image edges
called diffusion coefficient cd(x), it corresponds to the
image Gradient (∇I) [7].
The basic anisotropic diffusion PDE in 1D anisotropic
diffusion is:
(11)
I (x, t) is a signal, x refers to signal axes and t refers to
the iteration step, cd (x, t) is called the diffusion
coefficient [2] [7]. The function that impedes
smoothing at the edges is the diffusion coefficient
cd(x).

where Cd1 privileges high-contrast edges over low
contrast ones, Cd2 privileges wide regions over
smaller ones, ∇I is image gradient, and Kappa (K) is
referred to as the diffusion constant or the flow
constant.

Kernel Functions
Where
That is, the kernel function represents a dot product of
input data points mapped into the higher dimensional
feature space by transformation
Gamma is an adjustable parameter of certain
kernel functions.
The RBF is by far the most popular choice of kernel
types used in Support Vector Machines. This is
mainly because of their localized and finite responses
across the entire range of the real x-axis.

4. EXPERIMENTAL RESULTS
Brain MRI image classification is an important task.
In proposing work image preprocessing is done with
median filtering and skull stripping method. It shows
better performance. The features were extracted and
SVM is used as a classifier.
Classification method KNN algorithm is one of data
classification methods which has strong consistency.
KNN algorithm does not show an accurate while
when compared to other two classifiers.
One of the best methods for classifying any image or
pattern is SVM. SVM is used to split a set of images
into two various classes. The classification is done by
finding the hyper-plane that differentiate the two
classes.
Among the MR images collected, 18 MR images are
diseased and 56 MR images are non-diseased or
normal images. The GUI menu option opens as in
Figure.

After the process of morphology and clustering, the

with its properties as in Figure.7. Also, on selecting
the option “RESULT”, the result of the tumor either
being normal, benign or malignant is displayed as in
Fig.9.

One of the best methods for classifying any image or
pattern is SVM. SVM is used to split a set of images
into two various classes. The classification is done by
finding the hyper-plane that differentiates the two
classes very well as given in Fig.9.
The inference drawn from the experimental results
shows that SVM proves to be as efficient as the
powerful tool ANN in decision making which is
proved applying to various images. Sometimes the
accuracy rate of using SVM method is little more than
ANN.

5. CONCLUSION
This method used to detect brain tumor from MR
images work accurately for almost many MRI images.
The performance of the method adopted uphold the
purpose of diagnosis for all types of MRIs. Further
advanced kernels or hybrid method associated with
support vector machines need to be designed to fit
universally for all MRIs. Thus classification
efficiency can be improved by adopting efficient
hybrid SVMs for large data-sets.
