| Abstract(in English) | Generally, PSNR (Peak Signal-to-Noise Ratio) is used as an index of the image quality objective evaluation, and it is necessary to prepare an original image. However, it is usually difficult to prepare the original images in case of CGM (Consumer Generated Media) movies such as YouTube etc. The authors have been working on blind PSNR estimation which estimates PSNRs of compressed and decoded videos without using original images and bit-stream analysis. In our previous study, we have estimated the quality of all frames to investigate its estimation accuracy, but we focus on quasi real-time implementation of our approach in this paper. In contrast with our conventional method, we sample the results of our blind PSNR estimation at a certain interval and interpolate PSNRs of other frames based on their AC power levels. |
