libsift is an algorithm to identify and locate interesting points within an image. For all such points, a descriptive signature is extracted. The signatures can be stored and matched among multiple images, allowing for a large number of interesting applications, such as aligning overlapping... Platforms: *nix

nu_corrector is a tool for correcting intensity non-uniformity artifact of image. Here, non-uniformity refers to image artifacts of vignetting and bias (e.g. intensity inhomogeneity, illumination etc.). This tool is an implementation of our single-image based vignetting or bias correction systems... Platforms: Matlab

We introduce an algorithm based on the morphological shared-weight neural network. Being nonlinear and translation-invariant, the MSNN can be used to create better generalization during face recognition. Feature extraction is performed on grayscale images using hit-miss transforms that are... Platforms: Matlab

Drupal has an aweful way of handling file requests through the private method. This module fixes that, it implements most of the HTTP features. Things likecaching and resuming are supported.This module also as a anti-leech feature which should prevent stealing of files on remote sites. So this... Platforms: PHP

The Matlab code in this folder implements 1D-3D NUFFTs via fast Gaussian gridding. The convolution loops are written as C programs to be compiled as mex files from the Matlab command prompt. Further mathematical details about the code can be found in L. Greengard and J. Lee, "Accelerating the... Platforms: Matlab
