The document discusses common image compression formats, including block transform and subband transform methods. For block transform, it describes the JPEG algorithm which uses discrete cosine transform (DCT) and quantization. For subband transform, it discusses developments like EZW and SPIHT, both of which use wavelet transforms and entropy coding like arithmetic coding. JPEG2000 is also covered as using tiling, DCT, and arithmetic coding like SPIHT.
