Title: The Innovations of Li Qu
Introduction
Li Qu is an accomplished inventor based in Fremont, CA. He holds 2 patents that showcase his expertise in digital video coding and image processing. His innovative approaches have contributed significantly to advancements in these fields.
Latest Patents
Li Qu's latest patents include "Coding of digital video with high motion content" and "Region-based scalable image coding." The first patent provides methods for coding the current frame of a video data bit stream. It involves creating and maintaining a global codebook of historic values for macroblocks of previous frames. The methods also include searching entries in the global codebook to find the best estimation of the current frame and calculating a measure of the difference between values for the two macroblocks. Additionally, it compares the effectiveness of the estimation macroblock provided by the global codebook entry to that provided by a motion compensation scheme. The best estimation method is then chosen, and the current frame is coded while updating the global codebook based on the new coded macroblock. The second patent discloses a region-based system, method, and architecture for encoding and decoding digital still images. This system produces a scalable, content-based, randomly accessible compressed bit stream by decomposing raw image data into a hierarchy of multi-resolution sub-images and defining a region mask to identify regions of interest.
