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
