Abstract
Some embodiments include determining a value of an identified pixel of a plurality of pixels of an image from a detector; determining a noise value based on the value of the identified pixel and the detector; determining a range based on the noise value and the value of the identified pixel; comparing the range and a value of at least one pixel of the pixels other than the identified pixel; and adjusting the value of the identified pixel in response to the comparison.
