Canonical decomposition of steerable functions
Yacov Hel-Or, Patrick C. Teo · 1996
Steerable functions find application in numerous problems in image processing, computer vision and computer graphics. As such, it is important to develop the appropriate mathematical tools to analyze them. In this paper, we introduce the mathematics of Lie group theory in the context of steerable functions and present a canonical decomposition of these functions under any transformation group. The theory presented in this paper can be applied and extended in various ways.
