Identifying the boundaries or edges of the tumor is necessary for the segmentation process in order to separate out the tumor from the given MRI image which may help further in proper detection of dimension of the tumor. This paper deals with identification of ROI based on threshold value. Locating discontinuities in an nosy image is cumbersome. In this paper an investigation is performed on different edge algorithms and also an attempt has been made to hybrid the existing edge algorithms to detect the boundaries more accurately and comparison is done based on the time complexity, area of the tumor in pixels, PSNR and MSE. The proposed techniques are checked for different MRI gray scale images to obtain conclusive result using Matlab.
