The code is for classic huffman compression with some raw data images.
(ie. Baboon and lena in raw,halftone and binary color)
- Clone directory to local
$ git clone https://github.com/yppan/rusty-huffman-unicode/ && cd rusty-huffman-unicode/- Encode(Compress):
$ cargo run -- -c <FILE>- Decode(Extract):
$ cargo run -- -d <FILE>This will not work now and will be explained below!
Due to the lack of the time, now I only focus on the experiment of different ways of huffman coding. Therefore Decoder is yet not fully workable
The basic decoder concept is the same as my previous project: rusty-huffman-unicode" You can check detail implementation there if you want.
Baboon
| Image(256*256) | Entropy(bit) | Before(byte) | After(byte) -without header | Header(byte) | Compression Rate |
|---|---|---|---|---|---|
| baboon_b | 0.96909 | 65536 | 8197 | 4 | 87.49% |
| baboon_halftone | 0.96136 | 65536 | 8197 | 4 | 87.49% |
| baboon_raw | 7.24065 | 65536 | 59939 | 146 | 8.54% |
Lena
| Image(256*256) | Entropy(bit) | Before(byte) | After(byte) -without header | Header(byte) | Compression Rate |
|---|---|---|---|---|---|
| lena_b | 0.96968 | 65536 | 8197 | 4 | 87.49% |
| baboon_halftone | 0.83681 | 65536 | 8197 | 4 | 87.49% |
| baboon_raw | 7.59536 | 65536 | 62932 | 214 | 3.97% |
