摘要： A novel method of using optical flow algorithm that maximizes the benefit of optical flow synthetic frames while minimizing the associated computation cost is provided. When using optical flow to produce synthetic frames between two actual/recorded frames, the method computes a set of estimates of optical flows (or a flow estimate) between the two frames. These flow estimates are then used to compute all synthetic frames that are needed between the two actual frames by interpolation, which creates each synthetic frame based on its temporal distances from the pair of actual frames.

摘要： A pixel interpolation method for interpolating a pixel value of a target pixel in a target picture is disclosed. The pixel interpolation method includes performing up-sampling upon the target picture for generating an up-sampled picture corresponding to the target picture, and interpolating the target pixel according to the up-sampled picture. The step of performing up-sampling upon the target picture includes interpolating and generating a third pixel in between a first pixel and a second pixel that are a pair of two adjacent pixels of each pixel line of the target picture, whereof a pixel value of the third pixel is an average of pixel values of the first pixel and the second pixel.

摘要： A method of enhancing picture quality of a video signal is disclosed. The method comprises the steps of generating an interpolated base frame image: receiving a first previously decoded difference picture; receding a second previously decoded difference picture; generating a combined motion compensated difference surface; and generating a temporally interpolated enhanced picture based upon the interpolated base frame image end the combined motion compensated difference surface. A circuit for enhancing picture quality of a video signal is also disclosed. The circuit comprises a base decoder generating a base image of a standard definition picture; a temporal predictive interpolator coupled to the base decoder and generating an interpolated block; and a summing circuit coupled to the temporal predictive interpolator. The summing circuit preferably adds the interpolated block and a difference block.

摘要： A system and method for motion adaptively filtering a de-interlaced video signal. This motion adaptive filtering may be accomplished by using a motion value determined during motion adaptive de-interlacing. The motion value may be used to adjust the amount of filtering to be applied to the de-interlaced signal. Edges in the signal representing motion my be filtered more than static regions. A pixel by pixel difference between multiple signal frames, calculated during motion adaptive de-interlacing, may be used to determine the motion value. A motion adaptive filter may be implemented either separately from the motion adaptive de-interlacer or incorporated as part of the motion adaptive de-interlacer.

摘要： Disclosed herein is a video signal processing method and apparatus. In an embodiment of the present invention, video having a second screen size is generated from input video having a first screen size through Wavelet/Bicubic video interpolation, and a parallel Projection Onto Convex Sets (POCS) method is applied to the generated video having the second screen size. In this embodiment, the video having the second screen size, which is generated through Wavelet/Bicubic video interpolation, is used as an initial value for the POCS method, and a motion component estimated based on the video having the first screen size and the video having the second screen size obtained through the use of the POCS method is used as a correction value for the POCS method. Accordingly, HD-class video can be rapidly produced from SD-class video without image degradation.
