Modified Hough Transformation for ROI

Region of interest (ROI) plays major role in the field of Radiology. It's a field of medicine that characterized for clinical health care and transmission of medical images and videos. The aim of ROI extraction is to decide which part of the brain image is affected. For transference of high resolution images, good compression techniques are needed. This is an important aspect in compressing resolution of images by avoiding process of unwanted image points. It provides better extraction techniques for better image extraction. In this paper, the modified Hough transformation technique which is the combination of both manual and automatic techniques is used. This technique was compared with different other techniques and provided good results. Some of the ROI classifications are discussed in literature review and implemented free-hand technique and automatic technique for extraction of important region in images.
