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 کاملFire Detection in Video Sequences using Optical Flow Estimation
Vision-based flame detection can be applied in large open spaces for fire detection, which has been achieved with camera surveillance systems. The motion estimator exploits some motion features such as color, shape and texture that are used to recognize fire and non-fire region. Classical systems applied optical flow estimation methods for flame detection which are based on the assumptions, for...
متن کاملMotion estimation in video coding using simplified optical flow technique
We propose an interpolation-free sub-pixel Motion Estimation (ME) technique that particularly aims at providing accurate Motion Vectors (MVs), where conventional sub-pixel interpolation ME algorithms used in video coding are too complex and time consuming. The proposed algorithm is a combination of block matching algorithms and simplified optical flow, which is Taylor approximation. The techniq...
متن کاملAn error analysis of camera translation direction estimation from optical flow using linear constraints
A linear method using optical ow to recover the translation direction of a moving camera has been previously presented. This algorithm produced a biased estimate and various compensation techniques have been proposed. The results of an error analysis of the diierent approaches containing expressions for the expected mean vectors and covariance matrices of the translation estimates are presented...
متن کاملOptical Flow with Geometric Occlusion Estimation and Fusion of Multiple Frames
Optical flow research has made significant progress in recent years and it can now be computed efficiently and accurately for many images. However, complex motions, large displacements, and difficult imaging conditions are still problematic. In this paper, we present a framework for estimating optical flow which leads to improvements on these difficult cases by 1) estimating occlusions and 2) u...
