@Namespace(value="cv::quality") @NoOffset @Properties(inherit=opencv_quality.class) public class QualityBRISQUE extends QualityBase
BRISQUE computes a score based on extracting Natural Scene Statistics (https://en.wikipedia.org/wiki/Scene_statistics) and calculating feature vectors. See Mittal et al. \cite Mittal2 for original paper and original implementation \cite Mittal2_software .
A trained model is provided in the /samples/ directory and is trained on the LIVE-R2 database \cite Sheikh as in the original implementation. When evaluated against the TID2008 database \cite Ponomarenko , the SROCC is -0.8424 versus the SROCC of -0.8354 in the original implementation. C++ code for the BRISQUE LIVE-R2 trainer and TID2008 evaluator are also provided in the /samples/ directory.
