Abstract: A fingerprint segmentation method and device is provided. The fingerprint segmentation method may include dividing a fingerprint image into a plurality of sub-images, pooling each sub-image to acquire a feature map of the fingerprint image, and segmenting the feature map based on a region growing algorithm to acquire a fingerprint region in the fingerprint image.
