SCANNER AUTOMATIC DIRTY/CLEAN WINDOW DETECTION

摘要

An image from a window of a scanner is taken and analyzed to determine whether the image is relevant to dirt or debris on the window. When the image is relevant to dirt or debris, the size and amount of the dirt or debris is compared to a threshold and when the threshold is exceeded an alert is raised to have the window cleaned of the dirt or debris.
