Abstract: Techniques for distributed foveated rendering based on user gaze are described. In an example, an end user device is communicatively coupled with a remote computer and presents images on a display based on gaze data. The user device receives a low resolution background image and high resolution foreground image from the remote computer based on the gaze data. The foreground image is constrained to a foveated region according to the gaze data. The end user device generates a composite image by scaling up the background image and overlaying the foreground image. The composite image is then presented on the display.

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.
