Optimum End-to-End Distortion Estimation for Error Resilient Video Coding
End-to-end distortion estimation plays an important role in error-resilient video coding. The intuitive method is to simulate the decoding process many times at the encoder, as used in the H.264 test model. However, the computing complexity is very high. In this paper, an optimum end-to-end distortion estimation scheme is proposed. Concretely, the correlations of the potentially propagated erro...
متن کاملAn 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 کاملError - Resilient Standard - Compliant Video Coding
In this chapter we review and compare two approaches to robust video transmission that can be implemented within the H.263 video compression standard. The focus of this chapter is on channel adaptive approaches that rely on a feedback channel between transmitter and receiver carrying acknowledgment information. Based on the feedback information, rapid error recovery is achieved by intra refresh...
متن کاملError Resilient Video Transmission over Wireless Networks
This report proposes a general architecture for error resilient video transmission over mobile wireless networks. Radio link layer, UDP Lite, and error control layer are combined to deal with high error rate in wireless environments. Both sender and receiver algorithms are given. An adaptive algorithm is further presented to automatically adjust parity data length in error control. The performa...
متن کاملError Resilient Schemes for Region of Interest based Video Coding
In video applications, not all regions of a particular frame are of equal importance. There are one or more regions in a video frame that have higher importance than the rest of the frame. In medical videos, only part of the frame is of high diagnostic importance. The medically important region can be coded with higher bit allocation. This paper reviews the current error resilient, region of in...
