Abstract
A method for detecting a dust spot () in a digital image () includes the steps of determining () an expected dust spot configuration () of the dust spot () in the image (); applying () a statistic order filter to a value channel of an HSV color space of the image to generate a filtered value for each pixel being evaluated (), the filtered value being based upon the expected dust spot configuration (); and comparing () the filtered value to an actual color space value of a plurality of pixels () in the digital image () to generate () a binary image (). In one embodiment, the method can also include the step of comparing () the binary image () to the expected dust spot configuration () to determine a probability of the presence of the dust spot () in the digital image ().
