This article presents a new digital image compression scheme which exploits a human visual system property-namely, recognizing images by their regions-to achieve high compression ratios. It also assigns a variable bit count to each image region that is proportional to the amount of information it co

Abstract
This paper presents a method for generating multi‐resolution adaptive triangulations of non‐manifold 3D objects composed of several regions with arbitrary geometry. The process first immerses the input boundary elements inside a semi‐regular adaptive tetrahedral mesh known as a BMT triangulation. The mesh elements are then pushed towards the boundary by means of a physically based compression scheme, more specifically, a mass‐spring system. The final triangulation has no degenerated tetrahedra and provides an approximation of the boundary based on a chosen resolution. Copyright © 2005 John Wiley & Sons, Ltd.
