摘要： Methods and apparatus, including computer program products, implementing and using techniques for performing temporal motion vector filtering in digital video are disclosed. A recursive hierarchical process is used to determine a motion vector. In the recursive hierarchical process, a neighborhood of old motion vectors is filtered to generate a first estimated motion vector for an image patch in a pair of two image frames. The filtering process uses multiple vectors in a neighborhood around the old motion vector to improve the prediction of the first estimated motion vector. The temporal vector partitioning process separates motion vectors associated with an object from motion vectors associated with a background before selecting a best motion vector, which improves the selection process. The process also works well in the absence of object/background boundaries, as in this case the outlier (incorrect) vector or vectors will be separated out from the good vectors.

摘要： Described herein is a method and system for the reduction of noise in a video sequence. When motion is present in the video sequence, this system and method identifies motion data. With the motion data, a Motion Compensated Temporal Filter (MCTF) can apply motion compensation prior to filtering in the time domain. Temporal filtering can be performed to reduce visible noise and other detrimental artifacts.

摘要： A motion estimation method and device are provided for processing images to be inserted, between a preceding original image and a following original image, into a sequence of images. Each image is divided into pixel blocks associated with motion vectors. For a current block of an image being processed, motion vectors associated with blocks of the image being processed and/or associated with blocks of a processed image are selected. Candidate vectors are generated from selected motion vectors. An error is calculated for each candidate vector. A penalty is determined for a subset of candidate vectors on the basis of the values of the pixels of the pixel block in the preceding original image from which the candidate motion vector points to the current block and/or on the basis of the values of the pixels of the pixel block in the following original image to which the candidate motion vector points from the current block.
