Huffman Compression - Pocket PC 2002 SDK

LEADTOOLS offers more compression options than any other Pocket PC 2002 toolkit on the market. LEADTOOLS supports industry standard and proprietary alternative compression algorithms including:

JPEG2000 JPEG
LEAD CMP LZW
RLE / PackBits ZIPLIB
CCITT G3/G4 Huffman
Arithmetic LEAD CMW

Huffman Compression

Huffman encoding is designed to work best on images that have a lot of repetition. The general concept is to assign the most used bytes fewer bits, and the least used bytes more bits. First, the most used bytes in the image are assigned a variable length binary code. The more often the byte is used the shorter the control code. The less often a byte occurs the longer the control code.
