We have developed a scalable image compression scheme with a good performance-complexity trade-off. Like JPEG, it is based on the 8x8 block discrete cosine transform (DCT), but it uses no additional quantization or entropy coding (such as Huffman or arithmetic coding). Encoding the DCT coefficients bit plane by bit plane, starting at the most significant plane, enables bit-rate or quality scalability. The individual bit planes are efficiently encoded using simple rectangular zones. Our method offers about the same compression performance as JPEG, but at a significantly lower complexity and with the additional feature of scaling the bit rate by simply truncating the generated bit string.
