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 …

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 …

The limited energy resources in portable multimedia devices require the reduction of
encoding complexity. The complex Motion Estimation (ME) scheme of H. 264/MPEG-4 AVC …

The limitation of energy in portable communication/entertainment devices necessitates the
reduction of video encoding complexity. The H. 264/AVC video coding standard is one of the …

Video stabilization is an important technique in present day digital cameras as most of the
cameras are hand-held, mounted on moving platforms or subjected to atmospheric …

In this paper we propose to use the discrete wavelet transform on the block motion vector
field for estimating the camera (global) motion parameters in the compressed domain. By …

Nowadays, as the amount of video content increases, the importance of global motion
estimation is increasing more and more. This paper considers motion estimation within a …

An error resilient technique using reversible data embedding in H. 264/AVC aiming at
recovering high quality under high loss rate is proposed. For compressed videos, since inter …

In this paper we propose a novel motion vector outlier removal technique for global (camera)
