Parallelization of the mathematical model of gabor filter

Abstract

Due to the acceleration of the informatization of modern society and the increase in the number of flows and objects of information that must be protected from unauthorized access, problems with the use of biometric identification technologies to differentiate access to information resources are becoming increasingly important. The paper discusses some features of fingerprint preprocessing procedures using the Gabor filter. A block diagram of a parallel model of software for fingerprint preprocessing is presented. Various technologies are also briefly considered that make it possible to organize an appropriate program (parallel processing), the advantages and disadvantages of each of them are described, on the basis of which the optimal one is selected for a specific task. The results on the speed of program execution with a different number of threads and their priority are provided.
