Latest Patents

One of his latest patents is titled "Quantization parameter map for video encoding with constant perceptual quality." This invention involves a processing apparatus and video encoding method that receive a portion of a video sequence. It determines complexities for blocks of pixels within that sequence. The quantization parameter values for these blocks are selected based on their complexities and the visually perceived coding artifacts produced. The blocks are then encoded using the selected values, decoded, and provided for display. Another notable patent is "Flash detection for video coding." This technique characterizes a frame as a flash frame and sets it as a non-intra frame. It prohibits the encoding of frames other than the flash frame with reference to it and applies a positive quantization parameter offset to the flash frame.
