Abstract

An automatic seal imprint comparing and recognizing method includes: - Convert the two seal imprint images to be compared into binary data; Calculate a character similarity of seal imprints, including: - Convert the binary seal-imprint images into thin lines; - Find the coordinates of a characteristic point of the thin lines in the image data of each seal imprint;and - Compare the coordinates of the characteristic points of the two seal-imprint image data and calculate the character structure similarity of the two seal-imprints using a formula; Calculate a line similarity of seal imprints, including: - Calculate the reference points of the two seal-imprint images; - Overlap the two seal-imprint images with the reference points as the center point; and - Calculate the line similarity of the two seal imprints; - Calculate an overall index of seal imprint similarity using the following equation: overall index of seal imprint similarity = (W1 x character structure similarity of seal imprints + W2 x line similarity of seal imprints) / W where W1 + W2 = W; and - Determine if the two seal-imprint images are identical based on a standard value.
