As each plane contains more signal energy than the lower significant layers together, the resulting bit-stream is scalable in the sense that it may be truncated at any position. The later the bitstream is truncated, the smaller the residual error when the image is reconstructed. For each bit plane, a zone or partition of bit plane is created that encompasses all the non-zero bits of the DCT coefficients in that bit plane. The partition is created in accordance with a strategy that is selected from a number of options in dependence of the content of the overall signal and/or the actual bit plane. A different zoning strategy may be used for natural images than for graphic content, and the strategy may vary from bitplane to bitplane. The form as well as other properties such as size of each partition can thus be optimally adapted to the content. Two-dimensional rectangular zones and one-dimensional zigzag scan zones may be mixed within an image or even within a DCT block. The selected zone creating strategy is embedded in the bitstream, along with the DCT coefficient bits in the actual partition. | 2012-04-19 |
