Latest Patent Applications
Cheng-Chang Lien has filed a patent application titled "SYSTEMS AND METHODS FOR PROCESSING SHADOWS IN COMPRESSED VIDEO IMAGES." This application discloses methods and systems for processing compressed video images. A processor detects a candidate object region from the compressed video images. The candidate object region includes a moving object and a shadow associated with the moving object. For each data block in the candidate object region, the processor calculates an amount of encoding data used to encode temporal changes in the respective data block. The processor then identifies the shadow in the candidate object region composed of data blocks each having the amount of encoding data below a threshold value.
Conclusion
Cheng-Chang Lien's work in video processing technologies showcases his innovative spirit and dedication to improving image quality in compressed formats. His contributions are poised to impact the field significantly.
