区域差分信息熵，一个用于评价超分辨率图像感知质量的评价指标。
The implementation of paper Regional Differential Information Entropy for Super-Resolution Image Quality Assessment. Under our assessment, the smaller the value, the better the perceptual quality.
opencv-python
numpy>=1.20.1
tensorflow>=2.3.0
keras>=2.4.3
Prepare paired images and call our method in RDIE.py. You can run demo.py for a try.
