Data Compression Device and Data Reduction Method Using Motion Characteristics of Video Object in Content-based Coding of Video

摘要

1. TECHNICAL FIELD OF THE INVENTION;Content-based Image Object Compressor and Data Reduction Method of Video.;2. The technical problem to be solved by the invention;Before encoding the sequence of each video object, we want to reduce the amount of image source data by measuring the motion size of each video object and removing the sequence of the video object during no motion.;3. Summary of Solution to Invention;If the video object movement between the previous frame and the current frame is smaller than a predetermined threshold and the video object movement between the latest frame and the current frame where the video object is not removed is smaller than the threshold, the video object of the current frame is removed and then Increasing the sequence number, and if not all are smaller, change the sequence number of the frame in which the video object is not removed to the current frame sequence number, and increase the current frame sequence number.;4. Important uses of the invention;Used for data compression device.
