Abstract
Software for image enhancement can implement operations including receiving an input image and saving the input image as a reference image. Operations can further include enhancing a brightness level of the input image to generate an enhanced input image. Operations can further include generating an upsampled image using the lowlight reference image and enhanced image. Operations can further include generating a noise reduced image by adjusting pixels of the enhanced input image based on a brightness invariant noise reduction algorithm and the reference image. Operations can further include implementing a sharpening algorithm on the noise reduced image to generate a display image.
