An adaptive threshold segmentation for detection of nuclei in cervical cells ...csandit
PAP smear test is the most efficient and easy procedure to detect any abnormality in cervical
cells. It becomes difficult for the cytologist to analyse a large set of PAP smear test images
when there is a rapid increase in the incidence of cervical cancer. On the replacement, image
analysis could swap manual interpretation. This paper proposes a method for the detection of
cervical cells in pap smear images using wavelet based thresholding. First, Wiener filter is used
for smoothing to suppress the noise and to improve the contrast of the image. Second, optimal
threshold is been obtained for segmenting the cell by various Wavelet shrinkage techniques like
VisuShrink, BayesShrink and SureShrink thresholding which segment the foreground from the
background and detect cell component like nucleus from the clustered cell images. From the
results, it is proved that the performance of the adaptive Wiener filter with combination of
SureShrink thresholding performs better in terms of threshold values and Mean Squared Error
than the other comparative methods. The succeeding research work can be carried out based on
the size of the segmented nucleus which therefore helps in differentiating abnormality among
the cells.

Comparitive study of brain tumor detection using morphological operatorseSAT Journals
Abstract
Segmentation divides an image into foreground object and the background object. In our case foreground object is brain tumor and background is CSF, white matter, and grey matter. Aim of our study is to detect the tumor and remove the background completely and compare the morphological operations that can be used for this purpose. Segmentation remains a challenging area for researchers since many segmentation methods results in over segmentation or under segmentation and hence, leads to the false interpretation of the results. The proposed work is the comparative study of the morphological segmentation methods for segmenting brain tumor from MRI images. Before segmentation, filtration process is carried out using two method, Non Local mean filter and median filter and their results are compared using MSE and PSNR. NL mean filter preserves sharp edges and fine details in an image hence, preferred over median filter. Also tumor location is identified, to get an approximate idea about the position of the tumor in the brain i.e. in which part the brain tumor is located. The tumor is identified by using different algorithms which are based on morphology such as watershed segmentation, morphological erosion, and hole filling algorithm and comparison between them is carried out based on parameters like accuracy, sensitivity and elapsed time. Each of the segmentation results are compared with the tumor obtained using interactive tool present in MATLAB R2013b.

SVM Classification of MRI Brain Images for ComputerAssisted DiagnosisIJECEIAES
Magnetic Resonance Imaging is a powerful technique that helps in the diagnosis of various medical conditions. MRI Image pre-processing followed by detection of brain abnormalities, such as brain tumors, are considered in this work. These images are often corrupted by noise from various sources. The Discrete Wavelet Transforms (DWT) with details thresholding is used for efficient noise removal followed by edge detection and threshold segmentation of the denoised images. Segmented image features are then extracted using morphological operations. These features are finally used to train an improved Support Vector Machine classifier that uses a Gausssian radial basis function kernel. The performance of the classifier is evaluated and the results of the classification show that the proposed scheme accurately distinguishes normal brain images from the abnormal ones and benign lesions from malignant tumours. The accuracy of the classification is shown to be 100% which is superior to the results reported in the literature.

Abstract
Brain tumour detection and segmentation is most important and challenging task in early tumour diagnosis. There are various
segmentation methods available but they are still challenging methods because of its complex characteristics such as ambiguous
boundaries and high diversity. To overcome this problem we are going to implement automatic brain tumour detection and
segmentation method by using local independent projection based classification. In this method we are going to consider tumour
segmentation as a classification problem. In this paper locality is important in calculations of projections. Also local anchor
embedding is used to solve linear projection weights. The softmax regression model is used to improve classification performance.
In this study we used MRI images as training and testing data. Finally the brain tumour is classified into tumour and edema
region. The area of tumour region is calculated in pixels.
Key Words: Brain tumour detection & segmentation, local independent projection based classification, local anchor

THE EFFECT OF PHYSICAL BASED FEATURES FOR RECOGNITION OF RECAPTURED IMAGESijcsit
It is very simple and easier to recapture a high quality images from LCD screens with the development of multimedia technology and digital devices. In authentication, the use of such recaptured images can be very dangerous. So, it is very important to recognize the recaptured images in order to increase authenticity. Even though, there are a number of features that have been proposed in various state-of-theart
visual recognition tasks, but it is still difficult to decide which feature or combination of features have more significant impact on this task. In this paper an image recapture detection method based on set of physical based features including texture, HSV colour and blurriness is proposed. Also, this paper evaluates the performance of different distinctive featuresin the context of recognition of recaptured
images. Several experimental setups have been conducted in order to demonstrate the performance of the proposed method. In all these experimental results, the proposed method is efficient with good recognition rate. Among the combination of low-level features, CS-LBP detection is to operator which is used to extract the texture feature is the most robust feature.

Abstract: These days analysing patient data in the form of medical images to perform diagnose while doing detection
and prediction of a disease has emerged as a biggest research challenge. All these medical images can be in the form of
X-RAY, CT scan, MRI, PET and SPECT. These images carry minute information about heart, brain, nerves etc within
themselves. It may happen that these images get corrupted due to noise while capturing them. This makes the complete
image interpretation process very difficult and inaccurate. It has been found that the accuracy rate of existing method is
very less so improvement is required to make them more accurate. This paper proposes a Machine Learning Model based
on Convolutional Neural Network (CNN) that will contain all the filters required to de-noise MRI or USI Images. This
model will have same error rate efficiency like those of data mining techniques which radiologists were interested in. The
filters used in the proposed work are namely Weiner Filter, Gaussian Filter, Median Filter that are capable of removing
most common noises such as Salt and Pepper, Poisson, Speckle, Blurred, Gaussian existing in MRI images in Grey Scale
and RGB Scale.

Diabetic retinopathy also known as diabetic eye disease, is when damage occurs to the retina
due to diabetes. It can eventually lead to blindness. By analyzing and detecting vasculature structures
in retinal image the diabetes can be detected in advanced stages by comparing its states of retinal
blood vessels. In blood vessel classification approach computer based retinal image analysis can be
used to extract the retinal image vessels. Stationary wavelet transform (SWT) are used to extract the
features from the fundus image and classification can be performed using Support Vector
Machine(SVM). SVM has become an essential machine learning method for the detection and
classification of particular patterns in medical images. It is used in a wide range of applications for its
ability to detect patterns in experimental databases. If the vessels are present, then it is extracted by
using segmentation. Mathematical morphology and K-means clustering is used to segment the vessels.
To enhance the blood vessels and suppress the background information, smoothing operation can be
performed on the retinal image using mathematical morphology. Then the enhanced image is
segmented using K-means clustering algorithm to detect the diseases easily.

During past few years, brain tumor segmentation in CT has become an emergent research area in the field of medical imaging system. Brain tumor detection helps in finding the exact size and location of tumor. An efficient algorithm is proposed in this project for tumor detection based on segmentation and morphological operators. Firstly quality of scanned image is enhanced and then morphological operators are applied to detect the tumor in the scanned image. The problem with biopsy is that the patient has to be hospitalized and also the results (around 15%) give false negative. Scan images are read by radiologist but it's a subjective analysis which requires more experience. In the proposed work we segment the renal region and then classify the tumors as benign or malignant by using ANFIS, which is a non-invasive automated process. This approach reduces the waiting time of the patient.

3. ABSTRACT
The influence and impact of digital image processing on modern society, science,
technology and art are tremendous and incredible. A stem cell considered to be
the undifferentiated biological unit cells is a kind of cell that can duplicate itself
over and over, providing new cells that can turn into cells with a specific
purpose. The stem cell analysis and research through the digital image
processing contributes its strong support to the doctors in the field of stem cell
research to yield the results in computerized technology rather than clinical
method. This kind of research through computerized method reduces the effects
on human body during transplantation and tends to be more time economical.
This project aims at computing the growth rate of stem cells by using
segmentation, feature extraction and pattern recognition which are the
fundamental methods of digital image processing. DRLSE algorithm is applied
for segmenting images. The DRLSE algorithm is an amalgamation of Canny
Edge Detector algorithm and DRLSE method, which uses the four well potential
function. Features are extracted from segmented images using GLCM method
and finally Support Vector Machine (SVM) is used for pattern recognition and
classification of stem cells.

9. CANNY EDGE DETECTOR
Developed by JOHN F.CANNY in 1986
Called optimal edge detector – satisfies three criterion:
Low Error Rate
Localized edges
Single edge response
10. CANNY-ALGORITHM
Apply Gaussian filter to smooth the image in order to remove
the noise
Find the intensity gradients of the image
Apply non-maximum suppression to get rid of spurious
response to edge detection
Apply double threshold to determine potential edges
Track edge by hysterises
In matlab canny is applied by using the keyword
e = edge (I,’canny’);

From this we can conclude tht the 2 striking features of stem cells is : self renewal & potency. Based on potency stem cell divided into types…given in slide 4
Bone marrow-tissue making blood cells,used whn umbilical sc not present.umbilical-taken from cord after baby born. Peripheral blood-done for BMT,sc separated from blood (donor) & blood returned to patients & sc injected. From aborted tissues sc taken-ethical issues.
Edge detection refers to process of identifying & locating sharp discontinuities=abrupt changes in pixel intensity.1.accurate detection of edges(as many as possible),2.dist.b/w edges found by detector & actual edge min,3.no false edge detection
1.Gaussian filter uses simple mask,performed using simple convolution method,larger the width lower is the sensitivity to noise,2.uses 4 dect to compute edges(hori,vertical=sobel; diag=roberts),sobel uses 3*3 mask,mag or edge strength & direction is calculated; 3.edge thinning,in the name itself,comparison of pixel with 1 abve & below or 90,180,135,0; 4.still some noise present,T1 & T2; 5.weak edges=either by noise or from true edge,blob analysis (N8)
Advantage:guide the direction of evolving contour
Mean square error (MSE) indicates the average difference of the pixels throughout the image. A higher MSE indicates a greater difference between the original and processed image. The PSNR computes the peak signal-to-noise ratio between two images, in decibels. This ratio is often used as a quality measurement between the original and a resultant image. The higher PSNR, the better the quality of the output image. To compute the PSNR , mean-squared error calculated is used
precision is the proportion of boundary pixels in the automatic segmentation that correspond to boundary pixels in the ground truth. Precision and recall are attractive as measures of segmentation quality because they are sensitive to over and under-segmentation, over-segmentation leads to low precision scores, while under-segmentation leads to low recall scores.
Recall is defined as the proportion of boundary pixels in the ground truth that were successfully detected by the automatic segmentation
The main goal of feature extraction is to obtain the most relevant information from the original data and represent that information in a lower dimensionality space. When the input data to an algorithm is too large to be processed and it is suspected to be redundant (e.g. the same measurement in both feet and meters, or the repetitiveness of images presented as pixels), then it can be transformed into a reduced set of features (also named a feature vector).
In 1973, Haralick introduced the co-occurrence matrix and texture features which are the most popular second order statistical features today.
From the word…it can be said tht it is a matrix.
Each element (i, j) in GLCM specifies the number of times that the pixel with value i occurred horizontally adjacent to a pixel with value j .
It works really well with clear margin of separation
It is effective in high dimensional spaces.
It is effective in cases where number of dimensions is greater than the number of samples.
It uses a subset of training points in the decision function (called support vectors), so it is also memory efficient.

Cons:
It doesn’t perform well, when we have large data set because the required training time is higher
It also doesn’t perform very well, when the data set has more noise i.e. target classes are overlapping
SVM doesn’t directly provide probability estimates, these are calculated using an expensive five-fold cross-validation. It is related SVC method of Python scikit-learn library.
