Applications examples

Edge preserving smoothing of vector-valued images

• Supports smoothing of vector-valued images (e.g. multispectral images, feature images)
• Linear complexity in number of color channels
• No discretization of color space required

Regularization for deconvolution

Inpainting

Quickstart:

• Run the script "setPath.m", it should set all necessary paths
• For best performance, increase Java heap space in the Matlab preferences (MATLAB - General - Java heap memory)
• Run a demo from the Demos folder
