Optimization of Calculation of Field Orientation Time and Binarization of Fingerprint Images

The field orientation and the binarization in an image are often used in fingerprint identification and authentication, and analysis of textures. The proposed algorithm reuses the additions and multiplications in the calculation of the field orientation using the switching property and uses the Digital Differential Analyzer (DDA) algorithm in the generation of convolution masks for the binarization of fingerprint images. The performance of the processing time and the result of the proposed binarization algorithm compared to the performance of algorithms that use convolutions masks were satisfactory compared to the other algorithms found in literature.
