摘要： A sequential-scanning process with motion information that compensates for inadequate motion estimation and motion compensation that would otherwise cause degradation of images, by correctly detecting errors arising from operations of motion estimation and compensation. Horizontal and vertical (filtered) patterns of each of motion-compensated (MC) and spatial-interpolated (SI) images are compared. If there is an error in the procedure of motion estimation, the process is carried out with a mixed (weighted) combination of the motion compensation and spatial interpolation or with the spatial interpolation only, instead of the motion compensation.

摘要： Provided is a method of removing noise from digital moving picture data reducing the number of frames used in a temporal filtering operation and able to detect motion between frames easily. The method comprises a method of spatial filtering, a method of temporal filtering, and a method of performing the spatial filtering and the temporal filtering sequentially. The spatial filtering method applies a spatial filtering in a YCbCr color space, preserving a contour/edge in the image in the spatial domain, and generating a weight that is adaptive to the noise for discriminating the contour/edge in the temporal filtering operation. The temporal filtering method applies temporal filtering based on motion detection and scene change detection, compensating for global motion, the motion detection considering the brightness difference and color difference of the pixels compared between frames in the temporal filtering operation, and a weight that is adaptive to the noise for detecting the motion in the temporal filtering operation. The spatial filtering method is preferably performed first, and the temporal filtering method is performed with the result of the spatial filtering.
