SDTV Quality Assessment Using Energy Distribution of DCT Coefficients
The VQM (Video Quality Measurement) scheme is a methodology that measures the difference of quality between the distorted video signal and the reference video signal. In this paper,we propose a novel video quality measurement method that extracts features in DCT (Discrete Cosine Transform) domain ofH.263 SDTV. Main idea of the proposed method is to utilize the texture pattern and edge oriented information that is generated in DCT domain. For this purpose,the energy distribution of the reodered DCT coefficients is considered to obtain unique information of each video file. Then,we measure the difference of probability distribution of context information between original video and distorded one. The simulation results show that the proposed algorithm can represent correctly the video quality and give a high correlation with the video DMOS.
