Patent Images

1. to a quantizing method for image, it is characterized in that, comprising:

  • Image block is converted, obtains the transform coefficient matrix of correspondence image block;

    According to the dividing mode pre-set, Region dividing process is carried out to described transform coefficient matrix;

    Add up the statistical value of the regional marked off;

    Carry out quantification adjustment according to the statistical value in region and the priori data of corresponding region to region corresponding in the transform coefficient matrix of image block, the priori data of described corresponding region is the statistical value obtained by the coefficient of the corresponding region in the transform coefficient matrix of the image block in the image in statistics selected digital image sequence.
