Title: Patricia Chiang: Innovator in Video Encoding Technologies
Introduction
Patricia Chiang is a prominent inventor based in Singapore, known for her significant contributions to video encoding technologies. With a total of 6 patents to her name, she has developed innovative methods and systems that enhance video processing efficiency.
Latest Patents
One of her latest patents is the "Adaptive Pre-Filtering System." This invention involves a method, system, and apparatus for adaptive pre-filtering that extracts tuning parameters from video data during the encoding process. It processes these parameters to generate control parameters that represent the properties of the video data. The invention couples these control parameters to a filter response, generates filter coefficients accordingly, and filters the video data using these coefficients before encoding. This adaptive filtering reduces the complexity of encoding by attenuating high-frequency signals, effectively decreasing the quantization step and minimizing compression artifacts.
Another notable patent is the "Apparatus and Method for Coding Block Boundary Detection Using Interpolated Autocorrelation." This invention processes input video frames to create a binary map of potential block boundary pixels, including both original and rescaled boundaries. The boundary pixel map is then converted into a boundary histogram, to which interpolated autocorrelation is applied to detect block sizes and offsets. This method accommodates both integer and non-integer sizes, and it includes a confidence measure to reflect the accuracy of the detection results. The output for the current video frame is further processed with information from previous frames to enhance temporal stability.
