Particularly, the accuracy of the motion estimation along the motion boundary is improved. Several methods based on the single pixel matching are discussed, and the simulation results show the usefulness of the proposed method. 展开 关键词: Single pixel matching Motion estimation ...
In this paper, we propose block-based motion estimation (ME) algorithms based on the pixelwise classification of two different motion compensation (MC) errors: 1) displaced frame difference (DFD) and 2) brightness constraint constancy term (BCCT). Block-based ME has drawbacks such as unreliable...

Reducing rate/complexity in video coding by motion estimation with block adaptive accuracy Classical block-based motion-compensated video coders need to find and code a motion field with one motion vector per image block. All motion vectors are c... J Ribas-Corbera,DL Neuhoff - International Soc...
The motion estimation technique for the analysis of video sequences is a coarse to fine procedure based on the block matching algorithm (BMA). The method makes it possible to estimate the movement of selected elements on the scene with a sub-pixel precision. It has been done by applying a ...
In this paper, we present a stereovision algorithm for real-time 6DoF ego-motion estimation, which integrates image intensity information and 3D stereo data in the well-known Iterative Closest Point (ICP) scheme. The proposed method addresses a basic problem of standard ICP, i.e. its inability...
based on HEVC. From the analysis of the relationship between the Lagrange multiplier and the background proportion, a Lagrange multiplier selection model for surveillance video is used. However, there is a large amount of static background regions which provide motion vectors equal to zero. Because...
This paper poses a kind of auto-adapted motion estimation fast search algorithms based on beginning forecast and early stop in the process of integer pixel motion vector search according to the characteristic of movtion estimation in AVS-M code process.Comparing with MVFAST algorithms,this algorithms...
