In mobile computing environments, a video encoder should be able to provide high quality of service, which is measured from two perspectives: first, the video quality at a given bit rate must be optimized; second, it should be able to efficiently utilize its power supply to prolong the battery operating time. In other words, it should be able to achieve low power consumption as well as lower video...
Motion estimation is a multistep process that encompasses techniques such as motion vector prediction, determination of search range and search patterns, and identification of termination criteria. Each of these techniques has several diversions that may suit a particular set of video characteristics. It would be hard to conceive a universal algorithm that can perform well for all kinds of video contents...
This paper proposes a median-bias fast priority search algorithm for motion estimation. The main characteristic of the proposed algorithm is that it adapts a priority median-bias search pattern enabling the identification of locations with higher probability of finding the motion vector. Moreover, based on the history of motion vectors, the algorithm includes a robust region detection technique to...
The embedded motion compensation model of the new H.264/AVC video coding standard dramatically increases the computational complexity of motion estimation. We propose a fast motion estimation algorithm using a hierarchical motion intensity structure to lower the computational complexity of the motion estimation in H.264/AVC. The proposed algorithm is mainly based on a multi-level motion intensity...
