Abstract
A new mesh model for images, which explicitly repre-
sents discontinuities (i.e., image edges), is proposed along
with a corresponding mesh-generation method that deter-
mines the mesh-model parameters for a given input im-
age. The proposed approach is demonstrated to be capable
of producing mesh-based image approximations of higher
quality (both objectively and subjectively) than those gen-
erated by the state-of-the-art error-diffusion (ED) method
of Yang, Wernick, and Brankov. For example, the image ap-
proximations produced by the proposed method are often
about 2.5 dB higher in PSNR than those produced by the
ED scheme.
