Latest Patents

One of his latest patents is titled "System and method for adaptively compensating distortion caused by video compression." This invention provides a system and method for adaptively compensating distortion caused by video compression. The method first conducts edge texture detection and block boundary detection on an image. It classifies the area where the pixels to be processed are located to determine whether the pixel is in a ringing artifact prone area or near the block boundary with blocking artifact. Next, according to the area of the pixel to be processed and the degree of distortion, the invention adaptively compensates for the distortion using different filtering strategies. This improves the image effect of low bit-rate transmission at the display end, satisfying the real-time requirement for high-definition and ultra-high-definition displays.

Another significant patent is the "Method for edge-directed adaptive image interpolation and VLSI implementation device for the same." This method involves computing the gradient magnitude and gradient direction of the source image. It obtains edge information by comparing the gradient magnitude with a local adaptive threshold value, where the edge direction is the vertical direction of the gradient direction. The method classifies edge direction and filters using edge information, dividing the image into regular edge regions and non-edge regions. Regular edge region interpolation is conducted along the edge direction, utilizing improved bicubic interpolation, parallelogram bicubic interpolation, and parallelogram bilinear interpolation based on local gradient information. Non-edge region image interpolation is conducted using an improved bicubic interpolation method based on local gradient information. The device comprises an edge information extracting module, an adaptive interpolation module, an input line field synchronous control module, and a scaling line field synchronous control module.
