The authors present 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 (1986)

Factor Screening experiments identify those factors with significant effect on a selected output. We propose a modification of Cheng's method as a new factor screening alternative for simulation models whose output has homogeneous variance and can be described by a second-order polynomial function. The performance of the proposed model is compared with several other factor screening alternatives through an empirical evaluation. The results show that the proposed method sustains its efficiency and accuracy as the number of factors or the homogeneous variance increases. However, its accuracy degrades as variance heterogeneity increases.
