PSF - PROBABILISTIC SCALE-SPACE FILTERING PROGRAM
Deepak Kulkarni, Kiriakos N. Kutulakos · NASA Tech Briefs · 1993
Probabilistic Scale-Space Filtering (PSF) computer program implements scale-space technique to describe input signals as collections of nested hills and valleys organized in treelike structure. Helps to construct sparse representations of complicated signals. Calculates probabilities, with extracted features corresponding to physical processes. Written in C language (49 percent) and Common Lisp (51 percent).
