Abstract
A method is presented for detecting occlusions on a color camera. The method includes: capturing an image of a scene using the camera; analyzing intensity of electromagnetic radiation forming the at least one image, where the intensity of the electromagnetic radiation is analyzed across the electromagnetic spectrum; detecting an occlusion on a lens of the camera based on variation of intensity of the electromagnetic radiation across the electromagnetic spectrum; and tagging the image with an indicator of the occlusion, where the tagging occurs in response to detecting an occlusion on the camera.
