Comprehensive Evaluation Metric for Image Quality
Based on the contrast sensitivity from EF characteristics (spatial frequency response curve), this method performs 2D multi-level wavelet decomposition on images. From the decomposed wavelet components, it extracts corresponding luminance, sharpness, and correlation metrics for each frequency band. The geometric mean of these three metrics is then arithmetically averaged with the inner product of frequency band weighting coefficients to form a comprehensive image quality evaluation metric.
