Arithmetic-Coding-Simulation

This project simulate the process of encode a image in JPEG 2000 format using Arithmetic Coding and compare its performent with huffman coding.

Arithmetic Coding: https://github.com/tommyod/arithmetic-coding.git

Sample Image Data Set: Random Image Sample Dataset

How to use

1. Install package

pip install -r requirements.txt

2. Encode

python scripts\encode_image.py

• Select image and channel (Red, green, blue, lumin)
• Program auto encode to 4 file json
  • Encode arithmetic
  • Arithmetic frequencies
  • Encode huffman
  • Huffman frequencies

3. Decode

python scripts\decode_image.py

• Select encode json
• Program auto decode to image
  • Find frequencies file
  • Find meta file

Since encode process only use one color channel, decode only have one channel.
