摘要
A fingerprint information processing method and apparatus in which the method includes: obtaining a fingerprint image; calculating an average value of shading values of pixels in a specific region based on a pixel with respect to each pixel of the fingerprint image, performing a first processing of calculating a sum of average values of shading values of pixels included in an expanded region while gradually expanding the specific region, and generating a first processing image for the fingerprint image using a first processing-performed value for each pixel; and forming a window including a predetermined region in the first processing image, and selecting feature points among pixels in a window region while moving the window.
