A objective quality assessment for the evaluation performance of a video transmission system as a basic step for construction of digital video transmission system between the spots and headquarter. Due to a limit of an analog video transmission system and the developments of various digital media and digital video standards, the need of introduce of a digital system are increased gradually. At this points, previously performance evaluations are performed and the quality assessment is the most important thing.
We can be divided quality assessment method by the subjective quality assessment and objective quality assessment. The subjective quality assessment method has some problems which are required high cost and much time to evaluate the quality. And because existing objective quality assessment method such that PSNR are based on an analog form, the correlation with subjective data is very low.
Therefore we design a new objective quality assessment method using Gabor wavelet transform reflecting HVS(Human Visual System). Designed objective quality assessment method is superior to other objective method such that PSNR or EPSNR. In this paper, we proposed objective quality assessment using Gabor wavelet can be used for performance evaluation and verification of video transmission system.
