Pixel transition values of camera images are computed in a first direction by comparing intensity differences between neighboring pixels with an upper threshold and a lower threshold and setting a corresponding pixel transition value. A low pass filter with respect to time and a spatial filter are applied to the pixel transition values. Pixels of potential artifact regions are identified by comparing magnitude values of the smoothed pixel transition values with a predetermined detection threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Static soiling detection and correction","description":"A method and device for detecting image artifacts.
