Error Resilient Schemes for Region of Interest based Video Coding
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2014, Vol 7, Issue 1
Abstract
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 terest video coding schemes, which improve the quality of region of interest in video coding. Delivery of video is still a relevant problem today due to the numerous challenges in preserving information integrity in error prone environment such as the Internet and wireless networks. The effect of data loss in the transported compressed bit stream may lead to objectionable visual distortion at the decoder. There has been a lot of research to remedy or minimize the effect of channel errors on compressed video streams. This paper reviews the current schemes for making the region of interest based video coding more error resilient
