An Automatic Brain Tumour Detection, Segmentation and Classification Using MRI Image
نویسنده
چکیده
The aim of the project is to detect and classify the brain tumor from MRI image. This project involves mainly 6 stages namely Input Image, Preprocessing, Segmentation, Post Processing, Feature Extraction and Classification. In this phase, 4 stages are implemented, Input image, preprocessing, segmentation and post processing. Input image reads the MRI brain image. Preprocessing mainly includes image smoothing and image enhancement. Image smoothing can be achieved by using Median Filter and which is followed by Image Enhancement technique which can be achieved by Sobel edge detect technique. The third stage is segmentation. In this project, brain tumor is segmented using Pillar KMeans algorithm. Pillar KMeans algorithm includes selection of pillar pixels for effective segmentation. The experimental result shows that the proposed algorithm can effectively segments the tumors from MRI. Post processing operations are applied on the image to clearly locate the tumor part in the brain.

متن کاملA Review on Brain Tumour Detection Using Image Segmentation
Tumour is an uncontrolled growth of tissues in any part of the body. Tumours are of different types and characteristics and have different treatments. Detection of tumour in the earlier stages makes the treatment easier. Here a brief review of different segmentation methods used for detection of tumour from Magnetic Resonance Imaging (MRI) of brain has been discussed. Finally we propose an auto...
