Claim 4:
5. The detection method according to claim 2, wherein classifying the first unit image set based on the first average grayscale value interval to form one or more grayscale classes comprises:
calculating an average grayscale value of each unit image of the first unit image set;
sorting the first unit image set based on the calculated average grayscale value of each unit image to generate an image sequence associated with the first unit image set; and
in the image sequence, classifying the first unit image set based on the first average grayscale value interval, so that the differences between the average grayscale values of all of unit images of each grayscale class are within the first average grayscale value interval.
