Abstract

The use of the Bezier surface as a smoothing filter for vector fields is studied. Advantages of the Bezier surface over the moving average filter are determined. The algorithm of adaptation of the filter aperture size is modified. The efficiency of adaptation of the aperture size in vector field processing in the problem of estimating the material strain by the method of digital image correlation is considered.
