MRI Image Segmentation Using Gradient Based Watershed Transform In Level Set ...IJERA Editor
Brain image classification is one of the utmost imperative parts of clinical investigative tools. Brain images
typically comprise noise, inhomogeneity and sometimes deviation. Therefore, precise segmentation of brain
images is a very challenging task. Nevertheless, the process of perfect segmentation of these images is very
important and crucial for a spot-on diagnosis by clinical tools. Also, intensity inhomogeneity often arises in realworld
images, which presents a substantial challenge in image segmentation. The most extensively used image
segmentation algorithms are region-based and usually rely on the homogeneousness of the image intensities in
the sections of interest, which often fail to afford precise segmentation results due to the intensity
inhomogeneity. This Research presents a more accurate segmentation using Gradient Based watershed
transform in level set method for a medical diagnosis system. Experimental results proved that our method
validating a much better rate of segmentation accuracy as compare to the traditional approaches, results are also
validated in terms of certain Measure properties of image regions like eccentricity, perimeter etc.

Brain tumor classification using artificial neural network on mri imageseSAT Journals
Abstract
In this paper, an attempt has been made to summarize the multi-resolution transformation and the different classifiers useful to
analyze the brain tumor using MRI. X-ray, MRI, Ultrasound etc. are different techniques used to scan brain tumor images.
Radiologist prefers MRI to get detail information about tumor to help him diagnoses. In this paper we have used MRI of brain
tumor for analysis. We have used Digital image processing tool for detection of the tumor. The identification, detection and
classification of brain tumor have been done by extracting features from MRI with the help of wavelet transformation. The MRI of
brain tumor is classified into two categories normal and abnormal brain. In this work Digital image processing has been used as
a tool for getting clear and exact details about tumor in earlier stages. This helps the physicians and practitioners for diagnoses.

Segmentation and Classification of Brain MRI Images Using Improved Logismos-B...IJERA Editor
Automated reconstruction and diagnosis of brain MRI images is one of the most challenging problems in medical imaging. Accurate segmentation of MRI images is a key step in contouring during radiotherapy analysis. Computed tomography (CT) and Magnetic resonance (MR) imaging are the most widely used radiographic techniques in diagnosis and treatment planning. Segmentation techniques used for the brain Magnetic Resonance Imaging (MRI) is one of the methods used by the radiographer to detect any abnormality specifically in brain. The method also identifies important regions in brain such as white matter (WM), gray matter (GM) and cerebrospinal fluid spaces (CSF). These regions are significant for physician or radiographer to analyze and diagnose the disease. We propose a novel clustering algorithm, improved LOGISMOS-B to classify tissue regions based on probabilistic tissue classification, generalized gradient vector flows with cost and distance function. The LOGISMOS graph segmentation framework. Expand the framework to allow regionally-aware graph construction and segmentation.
Automatic Brain Tumour Detection Using Symmetry InformationIJERA Editor
Image segmentation is used to separate an image into several “meaningful” parts. Image segmentation is identification of homogeneous regions in the image. Many algorithms have been elaborated for gray scale images. However, the problem of segmentation for color images, which convey much more information about objects in scenes, has received much less attention of scientific community. While several surveys of monochrome image segmentation techniques were published, similar surveys for color images did not emerge.
Image segmentation is a process of pixel classification. An image is segmented into subsets by assigning individual pixels to classes. It is an important step towards pattern detection and recognition. Segmentation is one of the first steps in image analysis. It refers to the process of partitioning a digital image into multiple regions (sets of pixels). Each of the pixels in a region is similar with respect to some characteristic or computed property, such as color, intensity, or texture. The level of segmentation is decided by the particular characteristics of the problem being considered. Image segmentation could be further used for object matching between two images. An object of interest is specified in the first image by using the segmentation result of that image; then the specified object is matched in the second image by using the segmentation result of that image
Today, computer aided system is widely used in various fields. Among them, the brain tumor detection is an important task in medical image processing. Early diagnosis of brain tumors plays an important role in improving treatment possibilities and increases the survival rate of the patients. Manual segmentation of brain tumors for cancer diagnosis, from large amount of Magnetic Resonance Imaging MRI images generated in clinical routine, is a difficult and time consuming task or even generates errors. So, the automatic brain tumor segmentation is needed to segment tumor. The purpose of the thesis is to detect the brain tumor quickly and accurately from the MRI brain image. In the system, the average filter is used to remove noise and make smooth an input MRI image and threshold segmentation is applied to segment tumor region from MRI brain images. Region properties method is used to detect the tumor region exactly. And then, the equation of the tumor region in the system is effectively applied in any shape of the tumor region.

DETECTING BRAIN TUMOUR FROM MRI IMAGE USING MATLAB GUI PROGRAMMEIJCSES Journal
Engineers have been actively developing tools to detect tumors and to process medical images. Medical image segmentation is a powerful tool that is often used to detect tumors. Many scientists and researchers are working to develop and add more features to this tool. This project is about detecting Brain tumors from MRI images using an interface of GUI in Matlab. Using the GUI, this program can use various combinations of segmentation, filters, and other image processing algorithms to achieve the best results.
We start with filtering the image using Prewitt horizontal edge-emphasizing filter. The next step for detecting tumor is "watershed pixels." The most important part of this project is that all the Matlab programs work with GUI “Matlab guide”. This allows us to use various combinations of filters, and other
image processing techniques to arrive at the best result that can help us detect brain tumors in their early stages.
Brain tumor detection and localization in magnetic resonance imagingijitcs
A tumor also known as neoplasm is a growth in the abnormal tissue which can be differentiated from the
surrounding tissue by its structure. A tumor may lead to cancer, which is a major leading cause of death and
responsible for around 13% of all deaths world-wide. Cancer incidence rate is growing at an alarming rate
in the world. Great knowledge and experience on radiology are required for accurate tumor detection in
medical imaging. Automation of tumor detection is required because there might be a shortage of skilled
radiologists at a time of great need. We propose an automatic brain tumor detectionand localization
framework that can detect and localize brain tumor in magnetic resonance imaging. The proposed brain
tumor detection and localization framework comprises five steps: image acquisition, pre-processing, edge
detection, modified histogram clustering and morphological operations. After morphological operations,
tumors appear as pure white color on pure black backgrounds. We used 50 neuroimages to optimize our
system and 100 out-of-sample neuroimages to test our system. The proposed tumor detection and localization
system was found to be able to accurately detect and localize brain tumor in magnetic resonance imaging.
The preliminary results demonstrate how a simple machine learning classifier with a set of simple
image-based features can result in high classification accuracy. The preliminary results also demonstrate the
efficacy and efficiency of our five-step brain tumor detection and localization approach and motivate us to
extend this framework to detect and localize a variety of other types of tumors in other types of medical
imagery.

Automatic brain tumor detection using adaptive region growing with thresholdi...IAESIJAI
Brain cancer affects many people around the world. It's not just limited to the elderly; it is also recognized in children. With the development of image processing, early detection of mental development is possible. Some designers suggest deformable models, histogram averaging, or manual division. Due to constant manual intervention, these cycles can be uncomfortable and tiring. This research introduces a high-level system for the removal of malignant tumors from attractive reverberation images, based on a programmed and rapid distribution strategy for surface extraction and recreation for clinicians. To test the proposed system, acquired tomography images from the Cancer Imaging Archive were used. The results of the study strongly demonstrate that the intended structure is viable in brain tumor detection.
Efficient Brain Tumor Detection Using Wavelet TransformIJERA Editor

This method saves time as well as it reduces the error which occurs in the method of manual detection. In this paper the tumor is detected using wavelet transform. MRI is an important tool used in many fields of medicine and is capable of generating a detailed image of any part of the human body. The tumor is segmented from the MRI images, features are extracted and then the area of the tumor is determined. PNN can successfully handle the process of brain tumor classification
Tumor Detection Based On Symmetry InformationIJERA Editor
Various subjects that are paired usually are not identically the same, asymmetry is perfectly normal but sometimes asymmetry can benoticeable too much. Structural and functional asymmetry in the human brain and nervous system is reviewed in a historical perspective. Brainasymmetry is one of such examples, which is a difference in size or shape, or both. Asymmetry analysis of brain has great importance because itis not only indicator for brain cancer but also predict future potential risk for the same. In our work, we have concentrated to segment theanatomical regions of brain, isolate the two halves of brain and to investigate each half for the presence of asymmetry of anatomical regions inMRI.

The focus of this paper is the use of image processing in tumor detection from the brain Magnetic Resonance Imaging (MRI). For the brain tumor detection, Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) are the prominent imaging techniques, but most of the experts prefer MRI over CT. The traditional method of tumor detection in MRI images is a manual inspection which provides variations in the results when analyzed by different experts, therefore, in view of the limitations of the manual analysis of MRI, there is a need for an automated system that can produce globally acceptable and accurate results. There is enough amount of published literature available to replace the manual inspection process of MRI images with the digital computer system using image processing techniques. In this paper, we have provided a review of digital image processing techniques in the context of brain MRI processing and critically analyzed them for the identification of the gaps and limitations of the techniques so that the gaps can be filled and limitations of various techniques can be improved for precise and better results.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

OPEN ACCESS
Brain Tumor Detection Based On Symmetry Information
Narkhede Sachin G, Prof. Vaishali Khairnar
Abstract
Advances in computing technology have allowed researchers across many fields of endeavor to collect and
maintain vast amounts of observational statistical data such as clinical data, biological patient data, data
regarding access of web sites, financial data, and the like.
This paper addresses some of the challenging issues on brain magnetic resonance (MR) image tumor
segmentation caused by the weak correlation between magnetic resonance imaging (MRI) intensity and
anatomical meaning. With the objective of utilizing more meaningful information to improve brain tumor
segmentation, an approach which employs bilateral symmetry information as an additional feature for
segmentation is proposed. This is motivated by potential performance improvement in the general automatic
brain tumor segmentation systems which are important for many medical and scientific applications.
I.
Introduction
In Image processing, edge information is the
main clue in image segmentation. But, unfortunately,
it can’t get a better result in analysis the content of
images without combining other information. So,
many researchers combine edge information with
some other methods to improve the effect of
segmentation [1] [2] [3].
Nowadays, the X-ray or magnetic resonance
images have became two irreplaceable tools for
tumours detecting in human brain and other parts of
human body [4][5]. Although MRI is more expensive
than the X-ray inspection, the development of its
applications becomes faster because of the MR
inspection does less harm to human than X-ray’s.
Segmentation of medical images has the
significant advantage that interesting characteristics
are well known up to analysis the states of symptoms.
The segmentation of brain tissue in the magnetic
resonance imaging is also very important for detecting
the existence and outlines of tumours. But, the
overlapping intensity distributions of healthy tissue,
tumor, and surrounding edema makes the tumor
segmentation become a kind of work full of challenge.
We make use of symmetry character of brain MRI to
obtain better effect of segmentation. Our goal is to
detect the position and boundary of tumours
automatically based on the symmetry information of
MRI.
II.
Literature Survey
In most of time, the edge and contrast of Xray or MR image are weakened, which leads to
produce degraded image. So, in the processing for this
kind of medic image the first stage is to improve the
quality of images. Many researchers have developed
some effective algorithms about it [4] [5] [6].
After the quality of image been improved, the
next step is to select the interesting objects or special
areas from the images, which is often called
www.ijera.com
segmentation. Many techniques have been applied on
it. In this paper, we mainly discuss the brain tumor
segmentation from MRI. For now, there are also some
very useful algorithms, such as mixture Gaussian
model for the global intensity distribution [7],
statistical classification , texture analysis, neural
networks and elastically fitting boundaries, etc. An
automatic segmentation of MR images of normal
brains by statistical classification, using an atlas prior
for initialization and also for geometric constraints.
Even through, Brain tumours is difficult to be modeled
by shapes due to overlapping intensities with normal
tissue and/or significant size. Although a fully
automatic method for segmenting MR images
presenting tumor and edema structures is proposed in,
but they are all time consuming in some degree. As we
know, symmetry is an important clue in image
perception. If a group of objects exhibit symmetry, it
is more likely that they are related in some degree. So,
many researchers have been done on the detection of
symmetries in images and shapes.
I developed an algorithm based on bilateral
symmetry information of brain MRI. Our purpose is to
detect the tumor of brain automatically. Compared
with other automatic segmentation methods, more
effective the system model was constructed and less
time was consumed.
III.
Problem Statement
Brain tumors are a heterogeneous group of
central nervous system neoplasms that arise within or
adjacent to the brain. Moreover, the location of the
tumor within the brain has a profound effect on the
patient's symptoms, surgical therapeutic options, and
the likelihood of obtaining a definitive diagnosis. The
location of the tumor in the brain also markedly alters
the risk of neurological toxicities that alter the
patient's quality of life.
At present, brain tumors are detected by
imaging only after the onset of neurological

symptoms. No early detection strategies are in use,
even in individuals known to be at risk for specific
types of brain tumors by virtue of their genetic
makeup. Current histopathological classification
systems, which are based on the tumor's presumed cell
of origin, have been in place for nearly a century and
were updated by the World Health Organization in
1999. Although satisfactory in many respects, they do
not allow accurate prediction of tumor behaviour in
the individual patient, nor do they guide therapeutic
decision-making as precisely as patients and
physicians would hope and need. Current imaging
techniques provide meticulous anatomical delineation
and are the principal tools for establishing that
neurological symptoms are the consequence of a brain
tumor.
There are many techniques for brain tumor
detection. I have used edge detection technique for
brain tumor detection.

The Proposed Mechanism
4.1. Our algorithm
Our algorithm composes of two steps. The
first is to define the bilateral symmetrical axis. The
second is to detect the region of brain tumor.

x

Figure.2. The bilateral symmetry axis is defined with
a straight line.
This kind of symmetry is not very strictly.
And, compared with normal brain MRI, the symmetry
characteristic is distorted for the existing of brain
tumor, such as the circumstance shown in Figure.3.a.

y
4.1.1 Symmetry axis defining
The first step of our algorithm is mainly
based on symmetry character of brain MRI. The
bilateral symmetry character is very obviously in four
MR Images of brain presented in Figure.1.
x
3(a)
3(b)
Figure.3. the symmetry axis can’t be defined with a
straight line in the brain MRI with tumors, so a curve
line is more convenient to describe it.
Figure.1. The bilateral symmetry character is very
obviously.
If without tumor in the brain or the size of
tumor is very small, the symmetry axis can be defined
with a straight line x = k,(y >= 0) , which separates the
image into two bilateral symmetry parts, show as
Figure.2.
For more convenient to describing symmetry
axis, a curve line ( y = f (x), x > 0, y > 0 ) is defined,
which is shown in Figure.3.b. From the edge map, the
edge point set Pe can be obtained. And then, we
calculate the edge-centroid Gi of every line according
to equation (1).
k
Gi=1/k ∑ Pi, j, P i,j, Є Pe
j=1
where, Gi is the abscissa of centroid in the i th line, k
is the edge point number in the i th line, whose
abscissas are Pi,1…Pi,k . So, based on the edgecentroids, we can use the least square method to get
the symmetry curve line y approximatively.

Methodology Used
There are many techniques for brain tumor
detection. I have used edge detection technique for

brain tumor detection. Edge-based method is by far
the most common method of detecting boundaries and
discontinuities in an image. The parts on which
immediate changes in grey tones occur in the images
are called edges. Edge detection techniques transform
images to edge images benefiting from the changes of
grey tones in the images.
VI.
Performance Evaluation
If cutting of brain image gives symmetry by axis
then there will not be chances of tumor this is
detected by first algorithm otherwise there will be
chances of tumor.
As in others there are various steps are required to
just identify whether there is tumor or not but in
this it shows exact region where tumor is
occurred.
The color image is changes into gray scale image
and then by reiterative processing the tumor is
getting identified.
Our purpose is to detect the tumor of brain
automatically.
Compared with other automatic segmentation
methods, more effective the system model was
constructed and less time was consumed.

Conclusion
At first, it checks the image can be divided
into symmetric axis or not. If it is divided into
Symmetric part then no tumor in brain and it can be
divided in curve shape then chances of tumor in
human brain. However, if there is a macroscopic
tumor, the symmetry characteristic will be weakened.
According to the influence on the symmetry by the
tumor, develop a segment algorithm to detect the
tumor region automatically.
