    摘要: Disclosed herein is a method for selectively filtering and encoding a video signal having at least one frame including a matrix of pixels. The method includes selecting a set of pixels within the frame, determining an initial performance measurement for the selected set of pixels, provisionally applying each filter to the set of pixels, determining a second performance measurement for each filter provisionally applied to the selected set of pixels, and applying the at least one filter to the selected set of pixels to generate a reconstruction of the frame if the at least one filter is determined to have a second performance measurement that is better than the initial performance measurement.

    摘要: Methods for decoding frames of compressed video information are disclosed. Each frame includes a plurality of blocks having a prediction stage parameter and a residual error attribute. One method includes categorizing each of the blocks into categories based on at least one of the prediction stage parameter or the residual error attribute, determining a loop filter strength value to each of the categories, and filtering the boundary adjacent to at least one of the blocks using the loop filter strength assigned to the category in which that block is categorized.

    摘要: A method for encoding and decoding a video signal having frames with blocks comprised of pixels. The method reduces the complexity of the video signal to be encoded by applying a filter scheme to the input data stream in an encoder and later reversing the filter scheme in a decoder. A number of filter schemes may be tested to determine the best filter scheme that most reduces the number of distinct color values per color plane. The best filter scheme is used to filter the data to be encoded. Filter information of the best filter scheme is included in the encoded data to enable the decoder to identify the best filter scheme in order to apply the best filter scheme in reverse to re-create the original data stream.
