2D tight framelets with orientation selectivity suggested by vision science
Hitoshi Arai, Shinobu Arai · JSIAM Letters · 2009
In this paper we will construct compactly supported tight framelets with orientation selectivity and Gaussian derivative like filters. These features are similar to one of simple cells in V1 revealed by recent vision science. In order to see the orientation selectivity, we also give a simple example of image processing of a test image.
