Image segmentation and approximation through surface type labelling and region merging
Y.S. Lim, K.H. Park · Electronics Letters · 1988
The letter presents a two-stage image segmentation and approximation method for an image coding application. The proposed method is based on the surface fitting of an intensity image by a second-order polynomial function. Experimental results show its much improved performance compared with the method of Kocher-Leonardi.
