Latest Patents

Wei-Na Chang holds a patent for an "Image processing system and spatial noise reducing method." This invention discloses an image processing system that includes a local variance estimator, a noise detector, and a spatial de-noise filter. The local variance estimator estimates each pixel of an input image signal to output a local variance value for each pixel. It generates a noise threshold based on these local variance values. The noise detector identifies which pixels indicate noise or image content according to the established noise threshold. Finally, the spatial de-noise filter processes the pixels identified as noise to produce a clearer output image signal.
