Hidden Markov Tree model of Contourlet Transform

MATLAB files that fit a hidden Markov tree model

Description

MATLAB files that fit a hidden Markov tree model to the contourlet coefficients of images. This package also includes functions that uses the model for denoising and texture retrieval applications. These functions are based on the journal "Directional Multiscale Modeling of Images Using the Contourlet Transform" by D. D.-Y. Po and M. N. Do, and require the Contourlet Toolbox, written by Minh N. Do, which can be obtained from this link:
http://www.ifp.uiuc.edu/~minhdo/software/
For detailed instructions on how to use this package, refer to the included readme file.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 7.2 (R2006a)
• Other requirements: These functions require the Contourlet Toolbox, written by Minh N. Do, which can be obtained from this link: http://www.ifp.uiuc.edu/~minhdo/software/

Great work!

I'm tried to use the toolbox, but I'm fail to compile the mex file. Please tell me how to compile HMT toolbox under Visual c++ 6.0?

good
