Learn how to use entropy coding and source coding to reduce the rate and distortion of quantized data in digital communication.

We introduce "Block Arithmetic Coding" (BAC), a technique for entropy coding that combines many of the advantages of ordinary stream arithmetic coding with the simplicity of block codes. The code is ...

Arithmetic coding is a form of entropy encoding used in lossless data compression. Normally, a string of characters such as the words "hello there" is represented using a fixed number of bits per ...

Learn how to optimize the trade-off between compression ratio and complexity in entropy coding, a technique that reduces data size in digital communication.

The arithmetic coding uses nearly exact probabilities which easily approaching theoretical compression rate limit (Shannon entropy), but at cost of much larger computational cost. Asymmetric numeral ...
