    Title: An adaptive temporal-spatial filter for MPEG decoded video signals
    Authors: Tsann-Shyong Liu;Long-Wen Chang
    教師: 張隆紋
    Date: 1995
    Publisher: Springer Verlag
    Relation: MULTIDIMENSIONAL SYSTEMS AND SIGNAL PROCESSING,Volume 6,Issue 3,Pages 251-262,JUL 1995
    Keywords: MPEG
    video sequences
    Abstract: A new adaptive post-processing algorithm for the MPEG decoded video sequences is proposed. The authors use a motion compensated averaging filter to reduce the noises in the temporal domain and an adaptive spatial filter to remove noise in the spatial domain and preserve the edge of different orientations in the image. A MPEG decoded video sequence called table tennis is processed by the proposed filter. The post-processed video sequence shows that its image quality is improved, especially of the moving objects.
