Latest Patents

One of his latest patents is titled "Spatial scalable compression scheme using spatial sharpness enhancement techniques." This invention discloses a video encoder/decoder that utilizes spatial scalable compression schemes to improve video quality. The scheme introduces various video enhancement techniques on the base layer, employing a picture analyzer to determine the optimal mix of these techniques. The analyzer compares the selected enhancements with the original full-resolution input signal to identify which pixels require a residual enhancement layer. Additionally, parameters defining the selected mix are transmitted to the decoder layer, ensuring consistency in the enhancement techniques used.

Another notable patent is the "Method for deriving an objective sharpness metric." This method provides a way to objectively assess the level of image sharpness across various images with differing degrees of sharpness. It utilizes sub-band frequency information and false edge information from both the original and sharpened video sequences to derive a comprehensive sharpness metric.
