摘要： A method for reducing memory resource utilization is disclosed, applied to simplify address space of a table. Values stored in address fields of an original table are analyzed to determine whether logical relationship is detected between the values. If the logical relationship is detected, the values stored in the original table are classified to multiple base values and corresponding reduced values to generate a transformation table. Values with the same logical relationship for base values and the corresponding reduced values are stored in a new and equivalent address field of a reduction table.

摘要： A watermark coding method and its recording medium utilize image interleaving and wavelet-based transformation to enhance the robustness of the image. The watermark series to be inserted is converted, encrypted, and modulated to increase the difficulty in decoding and restoring. Finally, the watermark is distributed and hidden in various frequency bands of the image in a frequency hopping way, generating a robust watermarked image. When used in a recording medium, side information produced during coding is recorded in the lead-in area of the recording medium to reduce the chances of illegal copying.

摘要： A method for processing video image is provided to perform a motion vector filtering process on the image after being processed by a motion estimation process. The motion vector filtering process adjusts the motion vectors derived for each block in a video sequence, so that the motion vector of each block and the actual moving direction of the corresponding object in the image tend to conformity. Then, the blocks with similar motion vectors are merged and blocks with radical motion vectors are corrected, thereby reducing distortion of the output image and the number of bits used to represent the motion information, which in turns increases the efficiency of compression process.
