An application of C-calculus to texture analysis: C-transforms

摘要

A method for the analysis and discrimination of textures, based on C-calculus, is proposed.The concepts of C-space and C-transform of a digitized signal are introduced as simple tools, well suited to the visualization of the filtering properties of C-calculus: C-filters are thus also defined and the “natural” role they seem to play in problems concerning textures is investigated in some practical instances. In particular, C-transforms of some sample textures are provided and texture classification in C-space is performed. Discrimination of objects against textural background is obtained by C-filtering, in an inherently parallel fashion.The philosophy involved in this approach is finally briefly discussed in a comparison with some extant methods.
