Abstract:
An image enhancement technique includes a filter that receives an input image and provides a low-pass filtered image that maintains a substantial number of edges therein. The low pass filtered image is provided a likelihood of being a sky color for each pixel of the low pass filtered image. The low-pass filtered image is filtered based upon a user selection to selectively enhance the sky color. The low-pass filtered image and the filtered low-pass filtered image are blended based upon the user selection based upon the likelihood. The blended image is combined with a high pass filtered input image to provide an enhanced image.
