Design of Biometric Recognition Software Based on Image Processing

In order to improve the biological characteristic analysis and recognition efficiency, biometric image analysis method is used for biological recognition, the design of biometric identification software is carried out to improve the dynamic recognition ability of biological images, a design method of biometric recognition software based on image processing is proposed. First of all, the infrared optical scanning technology is used to scan the biological images, and the edge contour features of the collected biological images are extracted. Texture feature information is extracted from biological images, the extracted biometric information is input into the embedded software system. In the design of biometric identification software, biological feature recognition software uses real time trigger PXI-6713 for biological image acquisition, software development is taken under the embedded Linux drive kernel, the software system of biometric identification is developed by using DSP and logic programmable PLC, and the optimization design of biometric software is completed. The test results show that the biometric identification system designed in this paper has a good ability to identify biological images, and the accuracy of biometric recognition is high.
