Latest Patents

One of Chen's latest patents is titled "Scalable accelerator architecture for computing video quality metrics." This invention discloses a scalable hardware accelerator designed to compute video quality metrics. The accelerator includes an application-specific integrated circuit that features buffer memory for storing reference and distorted frames of a video. It also contains a processing unit that computes a perception-based video quality metric for the distorted frame in relation to the reference frame.

Another notable patent is "Systems and methods for histogram-based weighted prediction in video encoding." This computer-implemented method involves selecting a reference frame and a current frame from a video stream. It collects histograms for both frames and generates a smoothed reference histogram. The method further includes determining a similarity metric between the smoothed reference histogram and the current histogram, applying weighted prediction during motion estimation if the similarity metric exceeds a threshold.
