Abstract
The purpose of abnormality extraction is to understand and identify the abnormality. It is very helpful to the physician to gain knowledge of the severity of the disease. Region based segmentation is used for this purpose. In abnormality extraction, the threshold detection is very important and it can be consider as the key factor of the Intelligent Diagnostic Imaging System. Image segmentation is to partition an image into meaningful regions with respect to a particular application. The segmentation is based on measurements taken from the image and might be grey level, colour, texture, depth or motion. Usually image segmentation is an initial and vital step in a series of processes aimed at overall image understanding. This paper describes the algorithm for threshold detection for abnormality extraction. Different algorithms are used for T1 and T2 MRI Images. This paper also explains the comparison of different segmentation techniques. MATLAB tools are used to do the segmentation. The intensity level of a particular abnormality is same in an MRI image slice. It can be iso-intense, hypo-intense or hyper-intense.
