File Information

Description

toobox_signal - image processing related functions.

This toolbox contains functions related to image processing, including

* images loading and generation.
* filtering and blurring functions.
* anisotropic and spacially variant filters.
* non-linear filtering (median, LIC, bilateral).
* High Dynamic Range image loading and equalization.
* total variation image processing (denoising and decomposition).
* non-wavelets image transforms such as local DCT.

* Various helpers functions.

10 Apr 2009	c0l0jar0	I simply wanted to use the median filter function but already I found that with all of the subfolders added to path there is no create_gaussian_filter function and it would appear that I will be unable to use this filter. Any solutions or have any idea why it is missing?
18 Oct 2009	Raymond Cheng	Thanks for your sharing.
30 Dec 2010	Thomas Clark	Thanks for this Gabriel, a very useful toolbox (especially for those who don't have the image processing toolbox, and even for those who do). One interesting point is that some of the files in this toolbox are actually under version control (a sourceforge SVN, I think) and have metadata associated with them. I added this toolbox to a repository which I'm using, and it caused total chaos. So for anyone using version control, the workaround is to manually recreate the directory structure, and copy across the files from the original (ensuring you don't copy hidden files etc). Problem solved.
