Using margin information to detect regions of interest in images

This paper presents a region of interest (ROI) detection scheme utilizing the color information of image margins. The presented scheme applies the flood-fill technique to remove the background of the input image with the help of the color information of the image margin, and then discovers the ROI that contains the subject matter. The experimental results show that the presented scheme can effectively find the ROI in images. It can deal with images with low DOF as well as high DOF. Moreover, it can detect the subject matter with colors close to the background colors.
