Reconstruction-Based Subband Image Coding for UDP Transmissions.. - Su, Wah (Correct)
....as heuristic optimizations based on the smoothness assumption of image pixels. One approach formulates spatial smoothness constraints into convex sets and derives a solution iteratively [14] Other approaches minimize the variations along 2 edge directions or local geometric structures [4, 11, 15]. Besides being computationally expensive, mistakes in detection of image structures may yield annoying artifacts and blurred edges. Sender receiver based schemes require senders and receivers to cooperate in error concealments. They are usually more e#ective because receivers can convey ....

....the sum of squared differences between the boundary pixels of the lost block and its surrounding blocks [77, 86] This smoothness measure often leads to blurred edges in the recovered image. The other approaches propose to minimize variations along edge directions or local geometric structures [35, 59, 83]. They require accurate detection of image structures, and mistakes can yield annoying artifacts in a reconstructed video. Temporal domain recovery exploits temporal correlation by replacing a corrupted block by its corresponding block on the motion trajectory in the previous frame [25, 33] The ....

....was shown that with a nonlinear directional filter applied to a lost image block, the received damaged image can be reconstructed faithfully with block lost rates of as high as 50 . This property has been used to develop an economic way to transmit coded images for low bit rate coding applications [9, 10]. The spatial directional interpolation scheme in [8] makes use of the local geometric information extracted from the surrounding pixels. Specifically, statistics of the local geometric structure is modeled as a bimodal distribution. The two nearest surrounding layers of pixels of the missing ....
....words, find the optimal X opt: X opt: arg min R( X)Rbudget (X) fD(X; X)g (1) where D(X; X ) is the distortion between X and X, and R( X) is the actual bit rate of X. The problem can be solved using the standard Lagrange multipliers optimization method as shown in [10]. It can also be easily solved using the optimal tree pruning algorithm in [11] In our case, the tree has only two layers. The root is the image X with all black blocks being dropped and interpolated. The initial tree has M leaves, each corresponding to a black block, i.e. all black blocks ....
