Approximation of intensity images with adaptive triangular meshes: Towards a processable compressed representation

Abstract:

This paper presents an iterative algorithm for approximating intensity images with adaptive triangular meshes ensuring a given tolerance (a maximum Root-Mean-Square error). At each iteration, the algorithm applies a non-iterative adaptive meshing technique. In this way, it converges faster than traditional mesh refinement algorithms. The performance of the proposed technique is studied in terms of compression ratios and speed, comparing it with an optimization-based mesh refinement algorithm and with JPEG. The main advantage of using adaptive triangular meshes as compact representations of images is that further processing can be directly applied in the 3D geometric domain. Hence, triangular meshes can be used as processable compressed representations of intensity images. 1
