A Novel Pooling Strategy for Full Reference Image Quality Assessment Based on Ha

The most perceptual Full Reference Image Quality Assessmentmetrics (FR-IQA) shared a common two-step model;local quality measurement, and pooling. In this letter, a novelpooling strategy based on harmonic mean is proposed topredict the final quality score in FR-IQA. In contrast to arithmeticmean, the harmonic mean tends to emphasize the contributionsfrom the local severely distorted regions or pixels inthe definition of assessment function using reciproc
