2, fingerprint image processing

prestigious hotel smart door lock system includes fingerprint area detection, image quality judgment, pattern and frequency estimation, image enhancement, fingerprint image binarization and refining, etc. Pretreatment refers to noise and pseudo features of fingerprint image processing with certain algorithms, the ridge structure is clear, characteristic information. Its purpose is to improve the quality of fingerprint image, improve the accuracy of feature extraction. Usually pretreatment process including normalization, image segmentation, enhancement, binarization and thinning, but the hotel smart door lock system based on the specific situation preprocessing steps are also different. 3, fingerprint feature extraction

extracted from the image after preprocessing of fingerprint feature points information, information including the type, parameters such as coordinate and direction. Hotel smart door lock system in the detail features of the fingerprint, usually including the endpoints, bifurcation point, isolated points, short, ring, etc. And ridge endpoints and branch point in fingerprint opportunities, more stable and easy to obtain. These two kinds of characteristics of fingerprint matching feature points, calculation results of feature extraction and the characteristics of the stored template of similarity degree. Smart door lock fingerprint identification system module 4:
