Problem Statement
In today’s world,
one of the reason in rise of mortality
among the people is BRAIN CANCER.
For detection of brain tumor, first we have to read the MRI
image of brain and then we can apply segmentation of the image.
Here we present an Efficient method for removing noise from
the MRI image as well as for brain tumor detection.

What is Brain Tumour?
 A tumor can be defined as any mass caused by abnormal or
uncontrolled growth of cells. This mass of tumor grows within
the skull, due to which normal brain activity is hampered.
 Which if not detected in earlier
stage, can take away the
person’s life. Hence, it is very
important to detect the brain
tumor as early as possible.

Motivation
The Motivation for doing this project is primarily an interest of
undertaking one of the best challenging j-component project in
an interesting area of research i.e., Brain tumor detection.
We hope that this is the opportunity to learn about a new area of
computing not covered in lectures was appealing. This brain
tumor detection is possibly an area that we might’ve worked
upon, if we were in that stream. But now we’ve luckily got a
chance to show-up our self by this j-component.

Introduction
Image Segmentation is the process of partitioning a digital
image into multiple regions or sets of pixels which are similar
with respect to some characteristic such as colour, texture or
intensity.
Adjacent regions are significantly different with respect to the
same characteristics.
Segmentation produces a set of non-overlapping regions whose
union is the entire image.
Segmentation algorithms for images generally based on the
discontinuity and similarity of image intensity values.

Introduction (cont.,)
 Therefore the choice of image segmentation technique is
problem dependent that has been considered. So in our project,
we made an attempt to pick up already segmented images
(which are more over much noise free) and further
smoothening the image using various types of filters and
analyse their effectiveness.
 Based upon, the result obtained by processing the image
through different filters, it is clear visible for a normal naked
human eye to detect the tumour in the image.

Objective
Our Main Objective of medical imaging of BRAIN TUMOR
- is to extract meaningful and accurate information from
these images with least error possible and
 Finally conclude whether it’s a tumor image or not.

A Noble Approach for Noise removal from Brain
Image using region filling
 Firstly, they started with image acquisition, then noise is
removed from the noisy image.
 According to them, noise means in MRI images there will be
some information regarding the institute etc.,
 So all that unnecessary information which is treated as noise will
be removed.
 Then they converted RGB to Grey scale image.
 After this, they started to apply region filling, means they
selected some particular region of interest, then they filled that
area.
 Finally applied some low range filters.

Automatic Segmentation framework for primary tumors
from Brain MRI’s using Morphological Filtering techniques.
 Used a weighted algorithm.
 Firstly to the image identified, the intensity is adjusted
 Then they performed Morphological Erosion & Morphological
dilation.
 This process is further followed by Image subtraction, then
they found the threshold value by making use of some
histogram techniques.
 thus they performed Binary thresholding continued by
morphological labelling.
 Finally the segmented tumor is processed or know clearly
by image masking.

Morphological based segmentation of
Brain Image for tumor detection
Three major phases, namely,
1. pre-processing, (includes steps like
converting it to gray from a colour image
followed by type-casting the image)
2. Image segmentation, (followed the concept
of Thresholding technique and edge based
detection, and some operators related to
that are applied)
3. Image post processing. (Using filters)

MRI Brain Tumour segmentation with region
growing method based on the gradients
and variances along and inside of the
boundary curve.
Based on the gradients and variances along and inside
of the boundary curve, which focuses on the
consistency of the region and the smoothness of
the boundary.
Finally, what I observed is that, they made it easy to
solve the problem of threshold selection, i.e., the
minimum of the function value is the optimum
result which corresponding to the desirable
threshold.

 They put forth a method for detection and segmentation of the tumor.
 The method is a segmentation process of 2D MRI image using various
