Abstract: In one implementation, a method includes receiving a warped image representing simulated reality (SR) content (e.g., to be displayed in a display space), the warped image having a plurality of pixels at respective locations uniformly spaced in a grid pattern in a warped space, wherein the plurality of pixels are respectively associated with a plurality of respective pixel values and a plurality of respective scaling factors indicating a plurality of respective resolutions at a plurality of respective locations of the SR content (e.g., in the display space). The method includes processing the warped image in the warped space based on the plurality of respective scaling factors to generate a processed warped image and transmitting the processed warped image.

Abstract: The invention provides a method of and apparatus for determining if a newly reported target is correlatable with target tracks already stored in a data base. Correlation is effected in stages rejecting uncorrelatable stored target tracks and accepting closely correlated target tracks and includes decision applying means for accepting a stored target track as a correlated track only under stringent conditions.
