发明名称 Fingerprint region segmenting apparatus, directional filter unit and methods thereof
摘要 A fingerprint region segmenting apparatus and methods thereof The fingerprint region segmenting apparatus may include at least one directional filter receiving an input fingerprint image and filtering the input fingerprint image to generate at least one directional image, a normalization unit normalizing the at least one directional image and a region classification unit dividing the normalized at least one directional image into a plurality of blocks and classifying each of the plurality of blocks. In an example, the classification for each of the plurality of blocks may be one of a foreground of the input fingerprint image and a background of the input fingerprint image. In an example method, a fingerprint may be segmented by segmenting a fingerprint image into a plurality of regions based on a plurality of directional images, each of the plurality of directional images associated with a different angular direction.
