Abstract
A method for improved compression and filtering of images for foveated transport applications. The improvements including calculating along at least one axis of the full-resolution image data set, the distance from the foveal point to edges of full-resolution image data set, calculating the distance from each edge of the full resolution data set to the closest point on a foveal region surrounding the foveal point, calculating the distribution of available space in the adjacent peripheral regions of the image using a compression parameter, and calculating a compression curve wherein the compression of both adjacent peripheral regions is such that neither side of the adjacent peripheral regions are compressed more than the other.
