| Abstract | We describe a novel recursive filter design technique for multi-scale "pyramid" transforms. The recursion in the design technique follows that of the pyramid construction, and allows us to solve a reduced design problem at each step. We demonstrate the use of this technique by designing filters of various orientation bandwidths for use in a "steerable pyramid" image transform. 1 1. INTRODUCTION Recursive multi-scale transforms (e.g., wavelets) are now a standard tool in signal and image processing. The steerable pyramid is a particular variant of this type of transform which has been found useful in a variety of image processing applications [1, 2, 3, 4]. In this linear decomposition, an image is subdivided into a collection of subbands localized in scale (they have octave bandwidth) and orientation (they have orientation bandwidths of 2ß=m, m an integer). The transform is computed recursively using convolution and decimation operations, and it is "self-inverting". 2 The advantages... |
