Efficient Block Matching Algorithm for Motion Estimation
Motion estimation is a key problem in video processing and computer vision. Optical flow motion estimation can achieve high estimation accuracy when motion vector is small. Three-step search algorithm can handle large motion vector but not very accurate. A joint algorithm was proposed in this paper to achieve high estimation accuracy disregarding whether the motion vector is small or large, and...
متن کاملTrue-Motion Estimation and Compensation with Multitemporal Block-Matching Search
Improvements in de-interlacing algorithms are fundamental to explore image quality potential on modern TV screen technologies. This paper presents a true motion vector verification algorithm based on multi temporal block matching strategy, applied to video de-interlacing. During field scanning, a block of pixels is selected, then a block with the same reference coordinates is extracted but in t...
متن کاملAn adaptive search length algorithm for block matching motion estimation
This paper presents a new fast search algorithm for block matching motion estimation called the adaptive search length (ASL) algorithm. The ASL algorithm adaptively varies the number of positions searched for each block while still maintaining control of the average number of searches per block for each frame. Experimental results show that the peak signal-to-noise ratio (PSNR) of decoded seque...
متن کاملAn Efficient Successive Elimination Algorithm for Block-Matching Motion Estimation
Low power VLSI video compression processors are in high demand for the emerging wireless video applications [1]. Video compression processors include VLSI implementation of a motion estimation algorithm. Many motion estimation algorithms are found in the literature. Some of them are fast but can not guarantee an optimal solution; they can be stuck in a local optima. Such algorithms are fast, co...
متن کاملBlock matching algorithm based on Differential Evolution for motion estimation
Motion estimation is one of the major problems in developing video coding applications. Among all motion estimation approaches, Block matching (BM) algorithms are the most popular methods due to their effectiveness and simplicity for both software and hardware implementations. A BM approach assumes that the movement of pixels within a defined region of the current frame (Macro-Block, MB) can be...
