A Novel Hybrid Approach for Fast Block Based Motion Estimation

Local Binary Pattern Approach for Fast Block Based Motion Estimation

With the rapid growth of video services on smartphones such as video conferencing, video telephone and WebTV, implementation of video compression on mobile terminal becomes extremely important. However, the low computation capability of mobile devices becomes a bottleneck which calls for low complexity techniques for video coding. This work presents two set of algorithms for reducing the comple...

An Effective Hybrid Search Algorithm for Fast Block Motion Estimation

Motion estimation plays a key role in video coding, but its computational complexity is very high. In order to improve the performance of motion estimation, a hybrid search (HS) algorithm is proposed, which uses coarse-to-fine search strategy based on the ergodicity feature of chaotic search (CS) and the accurate feature of small cross search (SCS). Coarse motion vector is found by CS algorithm...

Adaptive 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...

Diversity-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...
