| A comparison of image quality models and metrics predicting object detection  (1995) Many models and metrics for image quality predict image discriminability, the visibility of the dfference between a pair of images.   We compared three such methods for their ability to predict the detectability of objects in natural backgrounds: a Cortex transform model with within-channel masking, a Contrast Sensitivity filter model, and digital image difference metrics.   Each method was implemented with three different summation rules: the root mean square difference, Minkowski summation with a power of 4, and maximum difference.   The Cortex model with a summation exponent of 4 performed best. comparison, detection, image, metrics, models, object, predicting, quality in J.
