Researching a machine learning algorithm for a face recognition system
This article investigated the problem of using machine learning algorithms to recognize and identify a user in a video sequence.
The scientific novelty lies in the proposed improved Viola-Jones method, which will allow more efficient and faster recognition of a person's face.
The practical value of the results obtained in the work is determined by the possibility of using the proposed method to create systems for human face recognition.
A review of existing methods of face recognition, their main characteristics, architecture and features was carried out. Based on the study of methods and algorithms for finding faces in images, the Viola-Jones method, wavelet transform and the method of principal components were chosen. These methods are among the best in terms of the ratio of recognition efficiency and work speed. Possible modifications of the Viola-Jones method are presented.
The main contribution presented in this article is an experimental study of the impact of various types of noise and the improvement of company security through the development of a computer system for recognizing and identifying users in a video sequence.
During the study, the following tasks were solved:
– a model of face recognition is proposed, that is, the system automatically detects a person's face in the image (scanned photos or video materials);
– an algorithm for analyzing a face is proposed, that is, a representation of a person's face in the form of 68 modal points;
– an algorithm for creating a digital fingerprint of a face, which converts the results of facial analysis into a digital code;
– development of a match search module, that is, the module compares the faceprint with the database until a match is found
