摘要： Systems and methods for hierarchical motion estimation are described. The hierarchical motion estimation may provide motion information and pixel correlation among temporal pictures at different resolutions, which may be utilized in motion related video processing applications such as video coding, motion compensation based denoising, interpolation, and others to improve the quality and/or speed of motion predictions. Systems and methods of video processing that include pre- and post-processing utilizing information from hierarchical motion estimations are also discussed. Specifically, systems and methods of video processing with hierarchical motion estimation instead of or in addition to other motion estimations are shown.

摘要： In a motion vector detection apparatus, cascade-connected processor elements each calculates the absolute value of the difference between each of a plurality of pixels which compose a picture and a corresponding one of the same number of pixels included in a block, and also performs cumulative addition of the difference absolute values in the block. These operations are performed for each of the blocks within the predetermined seach area.

摘要： The systems and methods described herein are directed at accelerating video encoding using a graphics processing unit. In one aspect, a video encoding system uses both a central processing unit (CPU) and a graphics processing unit (GPU) to perform video encoding. The system implements a technique that enables the GPU to perform motion estimation for video encoding. The technique allows the GPU to perform a motion estimation process in parallel with the video encoding process performed by the CPU. The performance of video encoding using such a system is greatly accelerated as compared to encoding using just the CPU.
In another aspect, data related to motion estimation is arranged and provided to the GPU in a way that utilizes the capabilities of the GPU. Data about video frames may be collocated to enable multiple channels of the GPU to process tasks in parallel. The depth buffer of the GPU may be used to consolidate repeated calculations and searching tasks during the motion estimation process. The use of frame collocation and depth buffer enables the GPU to be better utilized and to further accelerate video encoding.

摘要： A video processing system, method and computer program storage device cooperate to provide a resource and performance efficient sub-pixel motion search operation. Using on the fly calculations it is possible to provide approximations of sub-pixel positions on one image with respect to another image in an image sequence. A sub-pixel position used to set a motion vector for an encoding process may then be identified with reduced processing and memory resources relative to conventional techniques. Also, by later performing a full encoding cost analysis on the earlier identified sub-pixel position, and keeping track of differences, an interpolation accuracy may be dynamically improved by applying the differences to subsequent image frames.
