SYSTEMS AND METHODS FOR DEBLOCKING SEQUENTIAL IMAGES BY DETERMINING PIXEL INTENSITIES BASED ON LOCAL STATISTICAL MEASURES

摘要

Systems and methods are presented for improving the quality of an image as perceived by the Human Vision System by smoothing block artifacts in an image. In one embodiment, smoothing is accomplished by identifying target pixels to be smoothed and then replacing the pixel values of the target pixels with values derived from statistically similar neighboring pixels. The statistically similar neighboring pixels are chosen based on specific measurement criteria from within a region identified to contain such neighbors.
