Good evening all
Please is that you can help me?
I need registration code file after the huffman coding.
I break my MRI medical image by DWT then I realized for LL with lossless jpeg and hl, lh, hh with DPCM then I apply the zigzag reading and huffman coding but still I want to save all this data in a file to obtient a compressed image.
thank you for you help

Hello every body;
my problem is i find the size of compressed image is very superior original image.
is that you can help me find a matlab code to save all this data to be compressed image size. Thank you in advance for helping me
is what my code is correct or not? please is what you can give me a registration code files to be compressed image

Your questions are disappearing because I am deleting them. You have posted the same question a dozen times. Do not post duplicate questions. Use one question per topic, and edit that one question if you need to clarify it or rephrase it.
I have been deleting your extra questions and merging them together, but you posted a lot of them, and my network is slow today, so it is taking me time to get all the information in to one place.
It appears that your first language is French. Some of the French terms you have been using in your question are not the same words that would be used in English, and people do not understand your question. If you post a copy of your question written in French, then I will use Google Translate to figure out what the English terms are.

You have asked about "registration" file. English uses some other term for the concept. If you post your original question in French, I will try to work out what you are asking.
