# Arithmetic-algorithm

A python compression and decompression program based on Arithmetic Coding.

# Introduction

Arithmetic coding is a way to encode a list of symbols into a single fraction f, where 0 ≤ f < 1.

#Type of data

compress gray scale image.

# How to use

put path of your image in sample.json file 

# Run main.py only

main will run automatically encode.py decode.py

# You can choose data type and Block_size

Block_size=4 && float64 are recommended.
