What is foveated imaging:

The word Foveated is derived from fovea. The fovea, also known as the fovea centralis, is a part of the eye, located in the center of the of the retina.  The fovea is responsible for sharp central vision (also called foveal vision), which is necessary in humans for reading, driving, and any activity where visual detail is of primary importance. The fovea has the highest density of Cones(pixels in the retina) in the center resulting in the sharp vision  and as we move toward the periphery the  density of Cones decreases and resolution becomes lower.

Foveated imaging is a  technique that imitates the bahaviour of the fovea in which the image resolution, or amount of detail, varies across the image according to one or more "focus points." A focus point indicates the highest resolution region of the image and corresponds to the center of the eye's retina, the fovea.

The location of a fixation point may be specified manually using a pointer as shown in the main page this site or automatically using a computer depending on a given criteria.

Blow is an example of a foveated imaging. An image with a uniform high resolution(fig. 1) and a Foveated version of the same image (fig.2) with the focus on the flower to the left.

Applications:

A Foveated Imaging system can be used to to reduce transmission bandwidth of video Images from a remote camera systems.
