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...

Fast Block-Matching Motion Estimation Using Modified Diamond Search Algorithm

This paper propose a new block matching algorithm for motion estimation. Four different block matching algorithms using for motion estimation are evaluated where no of computation to find out best match and peak signal to noise ratio (PSNR) are used to find out most optimal algorithm. Four different block matching algorithm are implemented in MATLAB. Each algorithm is evaluated using PSNR and s...

Classification-Based Adaptive Search Algorithm for Video Motion Estimation

A video sequence consists of a series of frames. In order to compress the video for efficient storage and transmission, the temporal redundancy among adjacent frames must be exploited. A frame is selected as reference frame and subsequent frames are predicted from the reference frame using a technique known as motion estimation. Real videos contain a mixture of motions with slow and fast conten...

A fast octagon-based search algorithm for motion estimation

Fast motion estimation technique plays a very important part in video compression standard. In this paper, we propose a novel algorithm using octagon-based search (OCTBS) pattern for fast block motion estimation. The proposed OCTBS algorithm can find motion vector with fewer search points than the diamond search (DS) algorithm. The speedup gain of the OCTBS method over the DS algorithm is more ...

An Efficient Search Algorithm for Motion Estimation

An efficient search algorithm using the principle of Hexagon-Based Search algorithm (HEXBS) for motion estimation called Hexagon-Based Fast Search algorithm (HEXFS) is proposed in this paper. The proposed algorithm combines the hexagon search algorithm and a two-step search algorithm which uses cross search patterns to reduce the huge calculation complexity. The experimental results show that t...
