All releases of GREYCstoration

2.9

15 Jun 2008 10:57

Release Notes: A new image cleaning mode was added (for the command-line only). It is based on diffusion PDEs on image patch space. It gives quite interesting denoising results when parameters are set correctly, sometimes better than with the traditional "-denoise" method.

2.6

08 Jan 2008 10:54

Release Notes: This release deals with RGB/YCbCr color bases, and processes only particular channels of a hyperspectral image. Only the command line version has been updated.

2.5.2

01 Aug 2007 17:06

Release Notes: This version is far less memory consuming than the previous one, can deal with very big images, and has processing modes for 16-bit/components and 32-bit float-valued images, as well as multi-thread support. It also provides a new plugin for the GIMP.

2.5.2.1

09 May 2007 23:58

Release Notes: This release consumes far less memory than the previous version (2.4.2), so it can deal with very large images. There are now processing modes for 16-bit/components and 32-bit float-valued images, as well as multi-thread support. A brand new plug-in for the GIMP is provided.

2.5

06 Mar 2007 23:03

Release Notes: Processing modes for 16-bit/components and 32-bit float-valued images were added. The code was cleaned up and the footprint was reduced.

2.3

27 Mar 2006 07:36

Release Notes: The regularization algorithm has been improved and now performs three times faster than previous versions. A edge-enhancement filter was added, allowing more sharply restored images. Some bugs with filenames containing spaces have been corrected.

2.2

11 Feb 2006 00:57

Release Notes: The algorithm is now ables to give a denoising quality criterion (the 'Peak Signal to Noise Ratio') after denoising an image that has been artificially corrupted by the user. This allows a numerical comparison with other existing denoising methods. The interface was modified to show the original, noisy, and restored images when the user has corrupted the image with artificial noise.
