Hi Nidhi,

You can follow below approach:

Create the Huffman Dictionary: Ensure you have the same Huffman dictionary (dict) that was used for encoding the image. This dictionary maps the symbols to their corresponding Huffman codes.
Decode the Huffman Code: Use the huffmandeco() function to decode the encoded data.

Here's a refrence code:

% Assume 'encodedImage' is the Huffman encoded data
% and 'dict' is the Huffman dictionary used for encoding
decodedImage = huffmandeco(encodedImage, dict);
decodedImage = reshape(decodedImage, originalHeight, originalWidth);
imshow(decodedImage, []);
