#11 Software: MatLab tools for multi-scale image pyramids

I've recently made available some of my MatLab tools for multi-scale
image processing. Briefly, the tools include:

- Fast (MEX) convolution routines, with subsampling and boundary-handling.
- Recursive multi-scale image decompositions (pyramids), including
Laplacian pyramids, QMFs, Wavelets, and Steerable pyramids. These
operate on 1D or 2D signals of arbitrary dimension. Data
structures are compatible with the MatLab wavelet toolbox.
- Fast (MEX) point-operations, histograms, histogram-matching.
- Synthetic image generation: sine gratings, zone plates, fractals, etc.
- Display routines for images and pyramids. These include several
auto-scaling options, rounding to integer zoom factors to avoid
resampling artifacts, and useful labeling (dimensions and gray-scaling).

The software runs in Matlab versions 4.2 and higher, and has been
tested on Sun and Macintosh platforms (it should, however, port easily
to others). The package includes a README file, and a TUTORIALS
subdirectory contains script files showing example usage.

The package is available as a gnu-zipped UNIX "tar" file, via
anonymous ftp from ftp.cis.upenn.edu (IP number 158.130.12.3) in the
file pub/eero/matlabPyrTools.tar.gz. You may also access it via an
internet browser from http://www.cis.upenn.edu/~eero.
