摘要：
The analysis of oriented features in images requires 2-D directional wavelets, for instance, in standard tasks such as edge detection or directional filtering. In addition we present here a new application, namely, a technique for determining all the (statistical) symmetries of a given pattern with respect to rotations and dilations. Examples are Penrose tilings, mathematical quasicrystals or various quasiperiodic planar point sets or patterns.
