Is Center-Surround mechanism implemented in opencv?

I am new to the concept of Biologically Salient Regions Detector, and I read some papers and they always use the mechanism of Center-Surrond to computer features intensity, color and orientation. I googled that mechanism but i did not find implementation of it by Opencv with Java API or in any other libraries.

Actually i want to create the saliency map, and as far as i researched, some features like intensity, color, orientation are to be computed by the center-surround mechanism/filter.

I read lot o publications and the best of them, just provided a pseudo code but still it lacks clarity. i mean if you have a question regarding detailed issues to have an idea how that filter works, that pseudo code would not help much.

Is the center-surround filter mechanism is implemented in Opencv or in any other library?

Please provide explanation using and pseudocode.

These links may point you in the right direction I hope.

And this link it to an early version of Itti and Koch's saliency model in Pythons OpenCV bindings.

Hope it helps.
