Abstract : A technique using Hough transform is described for detection of homogeneous line segments directly from (i.e., without binarization of) gray level images. A definition of region in terms of these line segments, with constraints on its length and variance, is provided. The algorithm is able to extract gray regions irrespective of their shape and size. The effectiveness of the method is demonstrated on Indian Remote-sensing Satellite(IRS) images.
