摘要:
A method and device for detecting image artifacts. 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.
