| Research Abstract |
Video coding in a prescribed bit rate generally makes degradation on the image quality in the spatio-temporal domain. This research, focusing on high-definition (HD) videos whose horizontal size exceeds 1000 pixels and the frames per second is around 60, has investigated and developed an optimal rate control and video-quality equalization techniques based on an estimation of a subjective video quality under encoding in a prescribed bit rate.
