In order to design a full-reference objective Image Quality Assessment (IQA) algorithm that consistent with subjective evaluation. Based on local feature extracted according to different algorithms and nonlinear properties of generalized means strategy
two pooling strategies were proposed to promote the ability to evaluate Structural Similarity Image Measurement (SSIM)
Gradient Structural Similarity Image Measurement (GSSIM) and Feature Similarity Index (FSIM). Numerical test was conducted in TID2008 and TID2013 database
selections of various distortion non-linear parameters as well as the changes of non-linear parameters among different distortion types were discussed. The results show that the application of general means strategies could promote the effectiveness of IQA algorithm. 4 kinds of objective evaluation indexes
which are Spearman's Rank-Order Correlation Coefficient (SROCC)
Pearson's Linear Correlation Coefficient (PLCC) and the Root Mean Square Error (RMSE)
indicate that the algorithm proposed herein is superior to the existing algorithm
proves the consistency with human visual system.
