From: talal hammouri on 23 Feb 2010 06:41 Hi all, I have used the following code from the wavelet toolbox help to compress true color image but i have the following remarks: - i have not understand most of the code especially using wpeppesrs.wtc - it takes long time to run the code - is there any simple code to compress true color image - if we want to compress other than this image(i.e wpeppers.jpg) what are the changes to this code since i;m not understand wpeppers.wtc. Thank you very much X = imread('wpeppers.jpg'); [CR,BPP] = wcompress('c',X,'wpeppers.wtc','spiht','maxloop',12); Xc = wcompress('u','wpeppers.wtc'); subplot(1,2,1); image(X); axis square; title('Original Image') subplot(1,2,2); image(Xc); axis square; title('Compressed Image - 12 steps - haar4') xlabel({['Compression Ratio: ' num2str(CR,'%1.2f %%')], ... ['BPP: ' num2str(BPP,'%3.2f')]}) delete('wpeppers.wtc') Hi |
