Computation of Orientational Filters For Real-Time Computer Vision Problems II: Multi-resolution Image Decomposition

Abstract Orientational filters have been used frequently for computer vision problems. Despite their strength in various vision problems, their use has been limited in real-time applications since they are computationally intensive. A previous paper presented separable approximation as a way to implement a real-time orientational filter operation with a small amount of hardware. This paper extends the result of the previous paper to a multi-resolution decomposition.
