Dictionary-Based Image Compressor

A C++ tool that compresses 8-bit grayscale RAW images using dictionary-based compression methods.

Build

make

./lz_codec [options]

Flag	Description
`-c`	Compress the input file
`-d`	Decompress the input file
`-i <file>`	Input file name
`-o <file>`	Output file name
`-w <width>`	Image width in pixels (required only for compression, must be $\ge$ 1)
`-m`	Use predictive model (pixel difference)
`-a`	Use adaptive block scanning mode (16x16 blocks)

Compress with model and adaptive scanning:

./lz_codec -c -i input.raw -o compressed.bin -w 512 -m -a

Decompress:

./lz_codec -d -i compressed.bin -o output.raw
