ABSTRACT:
A system and method for noise filtering digital images is implemented in an automated image enhancement system without significantly reducing the performance of the automated image enhancement system. The system and method trigger a noise filter based on image measurements. If the image measurements indicate that the likelihood of objectionable "noise" in the image is high, a noise filter is triggered. Otherwise the noise filter is not triggered. In this way, only images that are in need of noise filtering are filtered, while other images are processed without the additional performance overhead required by the noise filter.
