# Multimedia Representation and Compression

compute entropy of an image, text; encode/decode text with huffman coding, LZW, LZ77; quantizatize image, signal

## Lab 2: Information Theory

- Compute Entropy of an image

- Compute Entropy of a text

## Lab 3: Lossless Compression - Variable length coding

- Encode/Decode a text with Hufman coding

## Lab 4: Lossless Compression - Dictionary techniques

- Encode/Decode a text into LZW format

- Encode a text by using LZ77 algorithm

- Compare compression ratio between Deflate and LZW

## Lab 5: Quantization

- Functions for uniform quantization (gray/color) image, signal
