Comparison of procedural textures generation algorithms for amorphous objects

The paper is devoted to algorithms for generating procedural textures, their estimations and comparison. Among wide variety of objects that can be produced with procedural textures, the most interesting are amorphous or gaseous phenomena. They imitate natural objects such as smoke, clouds, or dust and must be compared between them in similarity. As a comparison criterion, an image power spectrum(1) is chosen with the goal to make process of tuning procedural texture parameters more formal and automated. The idea to compare power spectrum characteristics of natural images and procedural textures is extended on larger set of parameters defining texture as well as on comparison of generation techniques.
