Abstract:
A fingerprint enrollment method and a fingerprint enrollment apparatus are provided. A minutiae feature and a pore feature of a first fingerprint image are extracted to obtain a first template. A minutiae feature and a pore feature of a second fingerprint image are extracted to obtain a second template. A minutiae matching score between the minutiae features of the first template and the minutiae features of the second template is calculated. When the minutiae matching score is between the first threshold and a second threshold, stitching, mosaicking or synthesis of the first template and the second template are performed by utilizing a matching relation between the pore features of the first template and the pore features of the second template and utilizing the matching relation between the minutiae feature of the first template and the minutiae feature of the second template.
