A HLAC Shape Descriptor Extraction Method for 3D Solid Textures

Texture mapping has become the most important method to increase the level of detail for a 3D computer graphics model without increasing its geometric complexity. Procedural texture synthesis methods have been used to generate solid textures for 3D models. These methods use noise functions and generate various solid texture patterns. The number of 3D solid texture databases on the web is increasing, and texture databases require systematic search methods for efficient retrievals. We have applied a 3D HLAC (Higher Order Local Autocorrelation) feature extraction technique to a search system which looks for similar patterns of the 3D solid textures from databases. 3D HLAC shape descriptors can classify similar texture patterns advancing the development of efficient search engines.
