Efficient approximation of gray-scale images through bounded error triangular meshes

Abstract:

This paper presents an iterative algorithm for approximating gray-scale images with adaptive triangular meshes ensuring a given tolerance. At each iteration, the algorithm applies a non-iterative adaptive meshing technique. In this way, this technique converges faster than traditional mesh refinement algorithms. The performance of the proposed technique is studied in terms of compression ratio and speed, comparing it with an optimization-based mesh refinement algorithm.
