I test your code and when I imshow the decompressed image, it has only black and white :v so I don't know how to restore color for decompressed image in matlab with your code, can you give me idea for this problem ?
Also, I want to calculate MSE, SNR and PSNR but it can't caculate in some picture, and your code run didn't well with .jpg, can you show me your idea for this problem too, please ?
Thank you.

Can LZW be used for fractional values?

I am currently working on some project and there I have fractional values that I want to encode.
I want to know if LZW is a good contender for encoding fractional values? Though from what I have realized that LZW is better utilized for strings or integer values. However is there any implementation of LZW that deals with fractional values?
