Snoweb lets you interactively edit noweb literate programming files in xemacs. Snoweb lets you contextually switch between tangled and untangled views of the document with a single keystroke, and your edits take effect in the noweb documentation regardless of which view you are in. This means you can use it the way you really edit code, rather than the way you'd write code if you had photographic memory and emitted perfect code from the start.
WAILI is a wavelet transform library. It includes some basic image processing operations based on the use of wavelets and forms the backbone of more complex image processing operations. WAILI uses integer wavelet transforms based on the Lifting Scheme, provides various wavelet transforms of the Cohen-Daubechies-Feauveau family of biorthogonal wavelets, crop and merge operations on wavelet-transformed images, noise reduction based on wavelet thresholding using Generalized Cross Validation, scaling of images, edge enhancement of images, some simple image operations (addition and subtraction of images), and allows different image representations (RGB, YUV, Lab, ...)
