Texture recognition by the shortest path on 3D discrete gray-level surface

In this paper, we apply geodesic paths (the shortest path which is an important object in the task of 3D shape analysis) to the description of natural textures. We first introduce an approach called propagation algorithm to estimate the shortest paths on discrete surfaces and then derive a set of texture features (LR, PLR, SDR, DIF and 1c) from them. The results of the experiments indicate that these features can reflect texture surface patterns in various aspects and are suitable for texture description.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
