In Multi-view Video Coding Scheme, the ability of view random access is an important performance to evaluate an encoding scheme's interactivity. At present, Multi-view Video Coding scheme based on H.264 standard makes data compression coding with both temporal and inter-view correlations. So, an efficient method to fetch the requested frame of view and time at small cost is needed, while making view...
The characteristics of video data are very large amount and real time processing request, and H.264 is a high-complexity video compression standard, so a high speed arithmetic is needed for encrypting video data which is encoded by H.264 standard. But, for a high security video application, it's difficult to find an algorithm to meet the two requests: high security, high speed. A new stream cipher...
This paper presents a new video quality metric for automatically estimating the perceptual quality of compressed video sequences. Distortion measures such as the mean squared error (MSE) and the peak signal to noise ratio (PSNR) have been found to poorly correlate with visual quality at lower bit-rates. The proposed quality metric (MOSp) predicts perceptual quality of compressed video using sequence...
