- W3406605 abstract "A two-layer coding approach with spatial pyramid to achieve compatibility [1] has been known to have several advantages. The first layer can have optimal performance, as it is done independently. Rate control can be distributed between layers. However, the compression performance and the overall complexity at the high resolution layer suffer because of the requirement of compatibility. Therefore, a good compatible prediction is a crucial factor for spatial scalability. In this paper, we focus on obtaining the best compatible prediction, assuming that a spatially upsampled block and a motion compensated block are available. A spatio-temporal averaging technique [1] has been shown to provide improvement. This technique can be improved by assigning the weights adaptively. The weights can be found by using a linear regression approach. Our study shows that a nonrecursive linear combination of spatial and temporal blocks has limited improvement. We will show that a recursive estimation technique can result in more improvement. We found that a pel-adaptive recursive estimation gives a good compatible prediction. However, pel-adaptive recursive filtering has to be modified to resolve conflicts with a block-based DCT compression scheme. We propose a motion compensated pel-adaptive Kalman recursive filtering method to provide such a solution. The additional complexity is moderate. The prediction gain after coding naturally will approach the gain before coding, as the coding algorithm becomes “more lossless”." @default.
