Ctf huffman

WebHuffman Coding is a famous Greedy Algorithm. It is used for the lossless compression of data. It uses variable length encoding. It assigns variable length code to all the characters. The code length of a character depends on how frequently it occurs in the given text. The character which occurs most frequently gets the smallest code. WebEncoding Process : Baseline DCT, Huffman coding. Bits Per Sample : 8. Color Components : 3. Y Cb Cr Sub Sampling : YCbCr4:2:0 (2 2) Image Size : 2560x1598. Megapixels : 4.1. …
