  • Patent number: 8249146
    Abstract: A method for selecting content adaptive coding mode can apply a critical value to update by taking the advantages of a content adaptive MCTF update method and a covered pixel detection algorithm and, at the same time, improve the image quality by selecting a block having improper motion information and converting it into a coding in screen mode. The method also provides a method for selecting content adaptive coding mode that can improve the conventional MCTF algorithm by reusing JND, which is used in content adaptive MCTF, to find a block that has improper coding information and selecting a block that has improper motion information.
