Early search termination for fast motion estimation
This paper proposes a novel method for early termination of a motion search. It first introduces an estimator of the sum of absolute difference (SAD) between the current block and a search point. After analyzing the SAD estimator, it proposes the SAD condition to decide whether the current search point is around a minimum point or not. The counter condition is used to evaluate the current searc...
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 کاملFast Motion Estimation using Circular Zonal Search
Block based motion estimation is widely used for exploiting temporal correlation within an image. Still the full search algorithm, which is considered to be the optimal, is computational intensive. In this paper a new fast motion estimation method for video coding, is presented. It will be shown that the new algorithm is not only much faster than traditional algorithms, but in some cases can ac...
متن کاملFast Motion Estimation with Search Center Prediction
This paper presents a new block based motion estimation algorithm that employs motion vector prediction to locate an initial search point, which is called a search center, and an outward spiral search pattern with motion vector refinement, to speed up the motion estimation process. It is found that the proposed algorithm is only slightly slower than Cross Search (CS), but has PSNR very close to...
