We propose a fast and robust 2D-affine global motion estimation algorithm based on phase-
correlation in the Fourier-Mellin domain and robust least square model fitting of sparse …

In many content-based video processing systems, the presence of moving objects limits the
accuracy of global motion estimation (GME). On the other hand, the inaccuracy of global …

In this paper, we propose an unsupervised segmentation algorithm for extracting moving
regions from compressed video using global motion estimation (GME) and Markov random …

Methods, apparatuses and systems may provide for technology that performs global motion
estimation. More particularly, implementations relate to technology that provides accurate …

Global motion estimation (GME) from motion vector (MV) field in compressed domain greatly
reduces the complexity of conventional pixel-based GME. However, outlier MVs, caused by …

Global motion estimation (GME) is a key technology in unmanned aerial vehicle remote
sensing (UAVRS). However, when a UAV's motion and behavior change significantly or the …

This paper discusses MAC-REALM, a framework for extraction of syntactic and semantic
content features and content modelling with either little or no user interaction. The framework …

Smart TVs have realized the convergence of TV, Internet, and PC technologies, but still do
not provide a seamless content interaction for TV-enabled shopping. To purchase …

Sprite coding, as standardized in MPEG-4 Visual, can result in superior performance
compared to common hybrid video codecs. We consider sprite coding, which significantly …

基于运动矢量场的视频全局运动估计相较于基于像素的估计方法具有较低的计算复杂度,
因而广泛应用于视频分割及视频压缩等领域中. 然而噪声和前景目标等外点区域的存在 …
