1. A method for selecting a pixel correction function, the method comprising:
displaying a plurality of pixels on a display that includes optical, mechanical, thermal and electrical (OMTE) display parameters;
selecting a subset of the plurality of pixels;
determining a mapping of pixel color, pixel intensity, and pixel position between the subset of pixels and one or more sensors;
deriving a pixel correction function based on the mapping and based on spatially varying weights corresponding to at least one of the pixel color or the pixel intensity;
applying the pixel correction function by modifying input image pixel data to produce corrected pixel data; and
driving the display with the corrected pixel data.
