2. ABSTRACT:
 The detection, and extraction of infected tumour from the collected data are a
primary concern but a tedious and time taking task performed by radiologists or
clinical experts, and their accuracy depends on their experience only
 In this project we aim to use basic image processing steps to detect the brain
tumor with the help of dataset in the form of GUI(GRAPHICAL USER
INTERFACE).
 If the detected image is not affected by brain tumor the output will display as
status message- “NO TUMOR”.
 If Detected image is affected by tumor the image processing step stakes place .

3. INTRODUCTION:
 Brain Tumor is a very serious type of malignancy that occurs when there
is an uncontrolled growth of cancer cells in the brain. Brain tumor is
caused by a malignant brain tumor.
 There are two main types of brain tumor.
 The Primary brain cancer is the rarest type of brain tumor. It can spread
and invade healthy tissues on the brain and spinal cord but rarely spreads
to other parts of the body.
 Secondary brain tumor is more common and is causedby a tumor that
has begun in another part of the body, such as lung tumor that spreads to
the brain.

4. DATA SET:
 We have collected data set from internet. From this data
set we are going to take random images for detection of
brain tumor. We use only MRI images of this dataset for
the Precise output.

5. EXISTING MODELS
This system utilizes image processing techniques, such as segmentation and feature extraction, to
automatically detect brain tumors in MRI or CT scans.

 D. Rammurthy , P.K. Mahesh, issued on 10 August, 2020.This paper proposes an
optimization-driven technique, namely Whale Harris Hawks optimization (WHHO) for
brain tumor detection using MR images

develop a unique technique for combining the colour channels made from multimodal
pictures to build an RGB image, highlight the tumour in MRI brain imaging, and find and
extract the tumour location from MRI images of people's heads.

9. OBJECTIVES:
 The objectives of Process of detection of Brain Tumor using MR image analysis
are broadly divided.
 Study of preprocessing of MR images. Image acquisition Adaptive filtering
 Study of Image Analysis of MR images Segmentation Feature Extraction
Enhancement Development of neural network algorithm for Classification and
Detection of Brain Tumor

10. DATA ACQUISITION:
 The data collected are grouped into two kinds—healthy brain images and
unhealthy brain images. Among the 66 patients, 22 patients have normal MRI
brain images and the rest 44 collect in the abnormal MRI brain image category
from the Harvard Medical School website (http://med.harvard.edu/AANLIB/)
 The MRI brain image obtained from the database were in the form of an axial
plane, T2-weighted, and 256 × 256 pixels. These images are scrutinized, and
preprocessing is done before the processing of algorithms.

15. OVERVIEW:

16. PREPROCESSING:
 The preprocessing step focuses on specifically removing the redundancy present
in the captured image without affecting the subtleties that play a key role in the
general procedure.
 It is done to improve the visual look and characteristics of an image. In the
conventional model, MRI images are often affected by impulse noise, such as salt
and pepper, which degrades the performance of the tumor segmentation system to
avoid the proposed skull stripping and morphological operations.

17. RESULTS AND DISCUSSION:
The suggested strategy was created using MATLAB software that has a Core 2 Duo
code configuration. Initially, the preprocessing technique is applied to enhance the
image. Next, the segmentation is applied to extract the boundary region of the tumor.

18. CONCLUSION:
 Medical image segmentation is a challenging issue due to the complexity of the
images, as well as the lack of anatomical models that fully capture the potential
deformations in each structure.
 This proposed method works very effectively to the initial cluster size and cluster
centers. The segmentation is done by using BWT techniques whose accuracy and
computation speed are less.
 This work recommends a system that requires negligible human intrusion to
partition the brain tissue. The main aim of this recommended system is to aid the
human experts or neurosurgeons in identifying the patients with minimal time.
 The experimental results show 98.5% accuracy compared to the state-of-the-art
technologies.
