Abstract: A method for creating a metamer for an image for a display, the method comprising receiving a first input image, dividing the input image into a plurality of regions comprising a foveal region and at least one peripheral region, wherein each region of the plurality of regions comprises a plurality of pixels, determining, for each of the at least one peripheral region, the distribution of statistics associated with each of the at least one peripheral region, for each of the at least one peripheral region, identifying a metamer for the peripheral region wherein the metamer has similar and/or identical distribution of statistics to the associated peripheral region, and creating an output image based on the foveal region and the metamer for each of the at least one peripheral region such that the peripheral region of the output image is perceived to be the same as the peripheral region of the input image when perceived by a viewer of the image.

Abstract: A method for rasterizing part of an image for a display, the image comprising one or more primitives, the method comprising for a first primitive in the image: calculating a distortion of the primitive, said distortion dependent on a determination of how the primitive will be perceived by a user when displayed on a display; distorting the primitive based on the calculation of the distortion to define a distorted primitive; defining a new primitive to be rendered by: bounding the distorted primitive with a polygon; and defining the new primitive based on the intersection of pixels from both the first primitive and the polygon of the distorted primitive.
