  • Publication number: 20040114825
    Abstract: A method of filtering video sources. A video having at least a first frame and a second frame and filter parameters is first received. Then, a designated portion of the body is set. Thereafter, an object and a corresponding face portion in the first frame are detected, and a skeleton of the object is determined. Then, the designated portion in the object is found according to the position of the face portion and the skeleton, and an adaptive filter is generated on the designated portion in the first frame. Afterward, the designated portion in the second frame is motion tracked, and another adaptive filter is generated on the designated portion in the second frame.

  • Publication number: 20020106021
    Abstract: A method and apparatus is used to reduce the unnecessary calculation of the video images motion estimation by identifying the all-zero block or zero-motion vector macroblock in advance. The method of computation reduction stops the motion estimation searching, referring to the condition of the absolute difference and the quantization parameter, and stops the following computation of the Discrete Cosine Transform and quantization. The reference critical value is set according to the motionless residue value of previous frame or the constant critical value to determine the zero-motion vector macroblock in the images.
