Matlab Toolbox of Multiscale Transforms for Image Fusion

You can download the source code for the latest multiscale tranfroms (sometimes called 'X-let' or 'Beyond Wavelet') from the following links:

Contourlet ,NSCT, Hidden Markov Tree Model of Contourlet
Sharp frequency localization contourlet(matlab toolbox)
Directionlet (Code is not shared now, but you can visit the author's webpage)
X-Let (Update the latest -let transform)

My main work are image fusion and denoising using these multiscale transforms, you can download my papers on the webpage (Publication) and found the code for image fusion and pulse coupled neural networks at webpage (software)

Welcome your comments, discussions and citations of papers of our research group.

Furthermore, if you are interested in these simulation code, please contact with my master degree advisor Prof.Yan (jwyan [at] or contact with me (quxiaobo <| at |>

Particularly, please inform us who you are, what your affiliation is and which parts of code you need.

Best wishes!
