Publicly Available Software Packages

• matlabPyrTools - Matlab source code for multi-scale image processing. Includes tools for building and manipulating Laplacian pyramids, QMF/Wavelets, and steerable pyramids. Data structures are compatible with the Matlab wavelet toolbox, but the convolution code (in C) is faster and has many boundary-handling options. [Last updated: Dec 2009, ver 1.4]

  UNIX/PC/mac-OSX source, or some fairly outdated Macintosh OS9 source.


• Two-stage functional model for steady-state responses of neurons in visual area MT. Matlab code now available.


• Image denoising code - Matlab code is available implementing a state-of-the-art algorithm for removing Gaussian noise (with known spectral properties) from images. The method is desribed in this journal article.


• Texture Analysis/Synthesis - Matlab code is available for analyzing and synthesizing visual textures. README | Contents | ChangeLog | Source code (UNIX/PC, gzip'ed tar file)


• EPWIC - Embedded Progressive Wavelet Image Coder. C source code available.


• The Steerable Pyramid, an (approximately) translation- and rotation-invariant multi-scale image decomposition. MatLab (see above) and C implementations are available.


• EPIC - Efficient Pyramid (Wavelet) Image Coder. C source code available.
