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...

Generalized partial distortion search algorithm for fast block motion estimation

The quality against speed control for real-time video applications, such as the speed-oriented video conferencing or the high quality video entertainment, usually absents from many traditional fast block motion estimators. In this paper, a novel block-matching algorithm for fast motion estimation named generalized partial distortion search algorithm (GPDS) is proposed. It uses halfway-stop tech...

Adjustable partial distortion search algorithm for fast block motion estimation

The quality control for video coding usually absents from many traditional fast block motion estimators. In this letter, a novel block-matching algorithm for fast motion estimation named the adjustable partial distortion search algorithm (APDS) is proposed. It is a new normalized partial distortion comparison method capable of adjusting the prediction accuracy against searching speed by a quali...

Normalized partial distortion search algorithm for block motion estimation

Many fast block-matching algorithms reduce computations by limiting the number of checking points. They can achieve high computation reduction, but often result in relatively higher matching error compared with the full-search algorithm. In this letter, a novel fast block-matching algorithm named normalized partial distortion search is proposed. The proposed algorithm reduces computations by us...

An adaptive partial distortion search for block motion estimation

Fast search algorithms for block motion estimation reduce the set of possible displacements for locating the motion vector. All algorithms produce some quality degradation of the predicted image. To reduce the computational complexity of the full search algorithm without introducing any loss in the predicted image, we propose a Hilbert-grouped partial distortion search algorithm (HGPDS) by grou...
