Popis:	In this work, we have designed a local descriptor based on the reassigned Stankovic time frequency distribution. The Stankovic distribution is one of the improved extensions of the well known Wigner Wille distribution. The reassignment of the Stankovic distribution allows us to obtain a more resolute distribution and hence is used to describe the region of interest in a better manner. The suitability of Stankovic distribution to describe the regions of interest is studied by considering face recognition problem. For a given face image, we have obtained key points using box filter response scale space and scale dependent regions around these key points are represented using the reassigned Stankovic time frequency distribution. Our experiments on the ORL, UMIST and YALE-B face image datasets have shown the suitability of the proposed descriptor for face recognition problem.
