Interpolation - Free Subpixel Motion
Currently existing subpixel motion estimation algorithms require interpolation of inter-pixel values which undesirably increases the overall complexity and data ow and deteriorates estimation accuracy. In this paper, we develop DCT-based techniques to estimate subpel motion at diierent desired subpel levels of accuracy in DCT domain without interpolation. We show that subpixel motion informatio...

متن کاملComprehensive scheme for subpixel variable block-size motion estimation
Fast variable block-size motion estimation is a key issue for real-time applications of the H.264, whereas the subpixel refinement takes up much computational time as compared to integer-pixel motion estimation. We propose a new fast subpixel precision variable block-size motion-estimation scheme. This algorithm uses the statistical information, which comes from the motion activities of the mac...
متن کاملAdaptive search area for fast motion estimation
In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...
متن کاملDiversity-based fast block motion estimation
Many fast search strategies reduce the complexity of motion estimation by limiting search locations, including the center-biased diamond search (DS), which performs better for small motion, and the nonbiased three step search (TSS), which works better for large motion. To achieve improved performance, we propose a diversity search strategy (DSS) by combining DS and TSS and applying them to deci...
