An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis
In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...
متن کاملMOTION AND VIDEO PROCESSING Processing Non Motion Compensated
In typical video sequences, the scene content remains principally the same from frame to frame. This implies that for tasks like noise reduction and missing data interpolation. There is much more data that can be usefully employed to reveal the underlying ‘original, clean’ data than with still images. For instance, consider a sequence showing a newscaster reading the news, and say that one of t...
متن کاملSegmentation-based Motion Estimation for Video Processing using Object-based Detection of Motion Types
In this paper, novel techniques for image segmentation and explicit object-matching-based motion estimation are presented. The principal aims of this work are to reconstruct motion-compensated images without introducing sig-niicant artifacts and to introduce an explicit object-matching and noise-robust segmentation technique which shows low computational costs and regular operations. A main fea...
متن کاملMotion Estimation Image and Video Processing
Image data in an image sequence remains mostly the same between frames along motion trajectories. This is the same as saying that the scene content does not change much from frame to frame. To exploit the image data redundancy in image sequences there is a need to estimate motion in the image sequence so one can process along motion trajectories After motion estimation, modules such as noise re...
متن کاملMotion Sensitive Pre-processing for Video
Due to the capture process, video signals are generally contaminated by noise. Furthermore, overall video quality can be improved by reducing sharpness in fast moving areas, except in cases where the eye is able to track the motion. In this paper we propose a relatively simple pre-processing method that is able to address both these situations. The proposed pre-processing algorithm is based on ...
