To recognize and classify any connected region-of-interest (ROI) in a digital image, the shape descriptor of the ROI has to be defined in terms of its boundary characteristics. However, for certain types of regions, it is very difficult to exactly trace the contour and none of the existing techniques satisfactorily work. In this paper, yConvex hypergraph model (yCHG) of digital image is introduced. It is a generalization of yConvex region decomposition [1] and represents any connected region as… CONTINUE READING
