ABSTRACT:
Embodiments of the present invention provide systems and methods for converting an achromatic, higher-resolution image to a lower-resolution image with reduced visible errors. These systems and methods comprise a sub-pixel sampling performed on a higher-resolution image. The sub-pixel sampled image is then converted to an opponent color domain image that is separated into separate luminance and chrominance channels. These chrominance channels are then high-pass filtered and combined with the luminance channel to form a filtered opponent color domain image.
