Hi
I am using a text file to hide inside an image file in lsb plane. But i want to compress the text file using huffman encoding and hide inside the lsb plane of image file. After retrieve the text file, the text file should be decompressed using huffman encoding.
Can you help in this matter.

A simple and easy way for encoding and decoding with a text file is give below:(We have used huffman functions in this code).
keep in mind make your text file in capital letters and with no nex line or comms or fullstop

By making a dictionay assigning their probabilities and using huffman commands like huffman enco this is where encoding part is. Also after running we can see the compression ratio or number of bits that are compressed just look it up.

Consider the given file(James C. Maxwell.docx). Compute the probabilities of alphabet and number (ratio of the number of occurrences to the total count of alphabets and numerals) and create a table with symbols and probabilities. Determine the Huffman code for the symbols and create the table of symbols and Huffman codewords. Using the above constructed table encode your name and Roll number.
