Abstract
Advanced driver assistance systems need to be able to operate under real time constraints, and under a wide variety of visual conditions. The camera lens may be partially or fully obstructed by dust, road dirt, snow etc. The invention shown extracts high frequency components from the image, and is operable to classify the image as being obstructed or non-obstructed.
