چکیده

In this paper we propose an efficient fast block-matching algorithm for motion estimation. Two different patterns, 3×3 and 5×5 cross patterns alternative in inner ring, and three search strategies, including prediction, threshold, and hierarchy, are utilized to form the procedure of the proposed algorithm. The simulation results show that number of search points required in the proposed algorithm is about 2-3% of full-search algorithm, 33-40% of diamond search algorithm, and approximated to that of dual-cross search algorithm while providing the competitive coding quality in comparison with both fast algorithms.

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...

New adaptive interpolation schemes for efficient meshbased motion estimation

Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...

Predictive and adaptive rood pattern with large motion search for H.264 video coding

We propose a fast motion estimation (FME) algorithm that performs comparably to the full search while having improved performance when compared to the best FME methods that are recommended for the JVT/H.264 standard despite having a much lower computational complexity than these methods. Our algorithm, called the predictive and adaptive rood pattern with large motion search, incorporates motion...

Adaptive Square-Diamond Search(ASDS) Algorithm for Fast Block Matching Motion Estimation

This paper presents an efficient search algorithm for fast block matching motion estimation(ME) for video applications. The algorithm uses two patterns for initial search and refined local search. For initial search, the proposed algorithm uses a square pattern adaptively by selecting the step size based on Maximum Absolute Value of predicted motion vector.
