  • Patent number: 9172977
    Abstract: Provided is a filtering apparatus, method, and medium for a multi-format codec, in which a blocking artifact of decoded video data is removed. The filtering apparatus includes a compression format detection unit, a block strength determination unit, a table determination unit, and a first filtering unit. The compression format detection unit detects a video compression format of the decoded video data. The block strength determination unit determines a block strength indicating a filtering strength with respect to the decoded video data according to the detected video compression format. The table determination unit determines a filtering table differently according to the block strength when the block strength is greater than a predetermined threshold. The first filtering unit performs filtering on the decoded video data in units of a block using the determined filtering table.

  • Patent number: 7684631
    Abstract: A method of and an apparatus for predicting discrete cosine transform coefficients. A discrete cosine transform coefficient prediction method and apparatus performs a discrete cosine transform on a row and column of pixel blocks nearest to a transform coefficient to be predicted in a discrete cosine transform block to be predicted among pixel blocks adjacent to the discrete cosine transform block to create a prediction coefficient for the transform coefficient to be predicted, and predict the transform coefficient to be predicted using the created prediction coefficient. By using prediction coefficients with higher correlation to a transform coefficient of a discrete cosine transform block to be predicted, an image may be efficiently compressed.
