<p>A method and system for automatically removing noise from images. First, a current pixel is received (300). Next an activity metric of the current pixel is computed (310) by using the current pixel and a neighborhoodo of pixels related to the current pixel. Then a distance metric that indicates the likelihood that the current pixel is a background pixel is computed (320) by using the activity metric and at least one background parameter. The distance metric provides a soft thresholding framework fo rthe background removal. The current pixel is modified (330) based no the distance metric.</p> |
