Pooling strategy for quality evaluation of full-reference model low illumination image
In order to design method for image quality evaluation of full-reference model more suitable under condition of low illumination imaging
aimed at attention characteristic for human vision and distortion characteristic of low illumination imaging
pooling strategy for quality evaluation with low illumination image based on context-aware was proposed. Through different distortion types
main object and its context information in image were provided with weighting by adopting specific weight methods in different spaces
and obtained Weighting Graph was used for Local Quality Diagram for similarity measurement of pooling characteristic to obtain final quality score. The experimental result shows that method in the Thesis is more satisfying to human visual characteristic
and root-mean-square error reaches 0.623 1
with Pearson linear correlation coefficient reaching 0.885 7
Spearman rank correlation coefficient reaching 0.885 6. Compared with other five mainstream methods
it has the optimal subjective visual consistence; at the same time
aimed at main distortion type of low illumination image
four kinds of objective evaluation indexes are superior to contrast method.
