摘要： A method conceals errors in an intra-fame of compressed video. The intra-frame is decoded to multiple macroblocks. Each macroblock including pixels arranged in a rectangular array. A lost macroblock is identified during the decoding. Pixels along an outer boundary of the lost macroblock are concealed from nearest candidate pixels along outer boundaries of macroblocks immediately adjacent to the lost macroblock. All other pixels in the lost macroblock are concealed from nearest candidate pixels selected from previously concealed pixels in the lost macroblock.

摘要： A method classifies pixels in an image. The image can be a decompressed image that was compressed using a block-based compression process. A filter is applied to each pixel in the image to determine a mean intensity value of the pixel. The mean is used to determine a mean-square intensity for each pixel, which in turn is used to determine a variance of the intensity for each pixel. The mean-square represents an average power of a DC component in the image, and the variance represents an average power of AC frequency components in the image. The pixels are then classified according to the variance as being either smooth, edge, or texture pixels. Blocks in the image can then be classified according to the classified pixels, and blocking artifacts and ringing artifacts in the blocks can then be filtered according to the block classification.

摘要： A method detects a boundary in a sequence of two-dimensional images where each image has multiple intensity value points. Filtering and motion analysis is applied on each image to produce motion enhanced images. Initial search parameters are determined from a dynamic snake model applied to the motion enhanced images. Each motion enhanced image is searched for a potential boundary using the search parameters. The potential boundary is projected into the motion enhanced image of a previous, current, and next image, and the search parameters of the previous, current, and next images are updated. The searching, projecting, and updating repeat until a predetermined level of convergence is reached.
