i use wcompress to compress gray scale image.know i have the original image X and compressed image Xc i want to know how to get the decompressed image and how to convert compressed image to binary (no of bit per pixel<8) http://www.mathworks.com/help/wavelet/ref/wcompress.html

load mask;       
[cr,bpp] = wcompress('c',X,'mask.wtc','spiht','maxloop',12)
% Then, it shows how to load the stored image from the file
% 'mask.wtc', uncompress it and delete the file 'mask.wtc'.
Xc = wcompress('u','mask.wtc');
delete('mask.wtc')
% The orginal and compressed images are displayed.
colormap(pink(255))
subplot(1,2,1); image(X);  title('Original image')
axis square
subplot(1,2,2); image(Xc); title('Compressed image')
axis square
