This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet.
For eg:-wavelets can be haar, db1, db2,dmey...............
Decomposition can be viewed in figure.
(Please note that select 256X256 image for better result.)
Then compression can performed,
PERFL2 give compression score.
Then reconstruction can be performed.
Each decompsition we can choose different threshold values.
For each threshold value we can calculate mse,psnr,pq(picture quality),
bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.

RSF_v0
This code demomstrates an improved algorithm based on the local binary fitting (LBF) model
in Chunming Li et al s paper:
"Minimization of Region-Scalable Fitting Energy for Image Segmentation",
IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008.
Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows.
Run the Demos in the M-files for several test images. Once an image comes out, click
the mouse to generate a polygon as the initial contour: left click to get
a number of points, then right click to get the end point.
The number of iterations may need to be increased if the initial contour is too far
away from the desired object boundary.
