Abstract

The research results of characteristics of various algorithms of PIV-images digital processing, obtained by a method of computer modeling, are considered. The comparative analysis of estimation methods of the shifts field of the PIV-images elements (a method of cross-correlation, a method of the minimum quadratic distance, a method of weighing and a phase method) is carried out.
