Visual discrimination model for single image applications

1. A computer implemented method for applying a visual discrimination model for single image applications comprising:

receiving an image;

defining a plurality of regions of interest in the image including a first region located to contain a feature to be detected and a second region located to encompass a background;

determining metrics for visibility of the feature, 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 in the image.

2. The computer implemented method of claim 1 , further comprising forming composite maps by combining the JND maps across channels.

3. The computer implemented method of claim 2 , wherein the channels are tuned to an orientation of the image.

4. The computer implemented method of claim 2 , wherein the channels are tuned to a spatial frequency of the image.

5. The computer implemented method of claim 1 , further comprising combining channel metrics to form feature vectors and compute the distance between vectors for the plurality of regions.

6. The computer implemented method of claim 1 , wherein the difference in the JND metrics between the plurality of regions is a measure of a dissimilarity of the plurality of regions.

7. A computer implemented method for applying a visual discrimination model for single image applications comprising:

receiving an image;

defining a plurality of regions of interest in the image including a first region located to contain an object to be detected and a second region located to encompass a background;
