Abstract
A computer implemented method for applying a visual discrimination model for single image applications includes receiving an image, defining a plurality of regions of interest in the image including a first region located to contain a feature or object to be detected and a second region located to encompass a background, determining metrics for visibility of the feature or object, wherein the metrics are determined by generating channel Just-Noticeable Difference (JND) maps for the single image determining JND summary metrics for the plurality of regions, and determining a difference in JND metrics between the plurality of regions, and adjusting parameters of the JND metrics to increase a visibility of the feature or object in the image.
