Abstract:
Aspects of the present invention are related to systems and methods for image enhancement, wherein an input image may be separated into two images: a first image comprising image content, from the input image, which may be sharpened; and a second image comprising image content, from the input image, which may be attenuated. One aspect of the present invention relates to determining a noise estimate associated with the input image and using the noise estimate to control the separation of the input image into the two images. Another aspect of the present invention relates to controlling the image separation based on the level of sharpening being applied to the first image.
