The Steerable Pyramid What is a steerable pyramid? The Steerable Pyramid is a linear multi-scale, multi-orientation image decomposition that provides a useful front-end for many computer vision and image-processing applications. The basis functions are directional derivative operators, that come in different sizes and orientations. The transformation is a type of overcomplete wavelet transform (specifically, it is an approximation to a "tight frame"). An example decomposition of an image of a white disk on a black background is shown to the right. This particular steerable pyramid contains 4 orientation subbands, at 2 scales. The smallest subband is the residual lowpass information. The residual highpass subband is not shown. The block diagram for the decomposition (both analysis and synthesis) is shown to the right. Initially, the image is separated into low and highpass subbands, using filters L0 and H0. The lowpass subband is then divided into a set of oriented bandpass subbands and a low(er)-pass subband. This low(er)-pass subband is subsampled by a factor of 2 in the X and Y directions. The recursive (pyramid) construction of a pyramid is achieved by inserting a copy of the shaded portion of the diagram at the location of the solid circle (i.e., the lowpass branch). More detailed descriptions may be found in the references (below). What advantages does it have over separable orthonormal wavelets?
