Systems and methods for image postprocessing via viewport demosaicing
An image postprocessor enhances the quality and detail of a rendered image by applying a photosite demosaicing technique directly to the pixels stored in the viewport of the rendered image. The image postprocessor detects a first subset of the viewport pixels having color values that deviate by more than a threshold amount from color values of a neighboring second subset of the viewport pixels. The image postprocessor maps the viewport pixels to a set of emulated photosites based on a position of each pixel in the viewport, and demosaics and/or interpolates the color values associated with a subset of the emulated photosites in order to generate new pixels for the gap. The image postprocessor replaces the first subset of pixels in the viewport with the new pixels, and presents a second visualization based on the modified pixels of the viewport.
