1. An apparatus, comprising: mapping logic configured to produce a high-resolution pixel from a low-resolution pixel; contour segmentation logic configured to classify the high-resolution pixel as being in a smooth region of an image based on at least one of a gradient value and a variance value associated with the low-resolution pixel; contour refinement logic configured to: identify a set of neighboring high-resolution pixels with respect to the high-resolution pixel; and selectively re-classify the high-resolution pixel as not being in the smooth region of the image when any pixels in the set of neighboring high-resolution pixels is classified as not being in the smooth region of the image; and range adjustment logic configured to selectively filter the high-resolution pixel based on whether the high-resolution pixel remains classified as being in the smooth region of the image, where the mapping logic is configured to produce the high-resolution pixel from the low-resolution pixel by operating on an individual color channel in a color space associated with the low-resolution pixel, and where the range adjustment logic is configured to selectively filter the high-resolution pixel in a different color channel of the color space.
