The Discrete Symmetry Transform in Computer Vision

By Vito Di Gesù, Vito Di Ges`u and Cesare Valenti


This report describe a new algorithm to measure local symmetry in a graylevels image. The introduced DST shows intresting properties of size and ro18 tation invariance; moreover it can be espressed as a local operator, given by the product of two filters. This allows to implement fast serial and parallel algorithms
