Abstract
Systems and methods for identifying and managing fixed sensor artifacts, such as scratches and non-operational sensor pixels, in a biometric sensor. A plurality of images acquired by the biometric sensor in response to detection of a biometric object proximal to a sensing surface of the biometric sensor are processed to determine a pixel value for each pixel location in each image. One or more specific pixel locations having substantially the same pixel value in the plurality of images are identified an artifact pattern of the biometric sensor.
