Steerable pyramid starter kit

Basic papers

• Simplified Design of Steerable Pyramid Filters (1998) by Castleman et al.
• The Design and Use of Steerable Filters (1991) by Freeman and Adelson
• Shiftable Multi-scale Transforms (1992) by Simoncelli et al.
• Image Denoising Using Scale Mixtures of Gaussians in the Wavelet Domain (2003) by Portilla et al. (more focus on denoising, but formulae for steerable pyramid in Fourier domain are here in appendix)

Mathcad files to design the pyramid

These files are slightly adapted versions of Mathcad files from Castleman

• Mathcad file to design the even filters (based on Mathcad files of Castleman)
• Mathcad file to design the odd filters (based on Mathcad files of Castleman)

Maple files to compute steering and dominant orientation

Calculation of dominant orientation based on Freeman & Adelson 91

• Maple file to compute steering for even filters
• Maple file to compute steering for odd filters

Spatial filter kernels

As output of the Mathcad files.

• Filter kernels (quadrature pairs) for the steerable pyramid
