In such a face detection and recognition technique, principal component analysis and linear discriminant analysis can be proposed. W. Zhao, R. Chellappa, A. Rosenfeld, and PJPhillips Quot; Face Recognition: A Literature Survey ", or WS ", published in ACM Computing Surveys in 2003, For example, consider the related art described by Yambor and published in the 2000 Technical Report of the College of Computer Science, Colorado State University, "Analysis of PCA-based and Fisher Discriminant-Based Image Recognition Algorithms".

Specifically, in performing face recognition, face matching is performed by comparing the characteristics of characters already stored in the character information DB with reference to features such as eyes, nose, mouth, face contour, hair, The face recognition rate can be increased.

In this paper, we propose a face matching method based on facial features. This paper describes a face matching technique called "Lucas-Kanade 20 Years On: A" by Baker, S. et al. And published in IJCV (International Journal of Computer Vision) Unifying Framework "for example. This paper describes a method for efficiently detecting an eye position from an image including a face of a person using a template matching method.

The face detecting unit and / or the face recognizing unit can estimate the position of the nose and the mouth based on the position of the eye detected by the above technique. The extracted parts of the eyes, nose, mouth, It is possible to increase the face recognition rate in comparison with the images related to the eyes, nose, mouth, etc. included.

Here, the search method of each part such as eyes, nose, and mouth is described by P. N. Belhumeur et al. As a face retrieval method, and the paper entitled " Eigenfaces ", which was published in 1997 IEEE TRANSACTIONS ON PATTERN ALAYSIS AND MACHINE INTELLIGENCE. Linear discriminant " disclosed in " Fisherfaces: Recognition Using Class Specific Linear Projection ".

The similarity of the whole face can be obtained by using a weighted sum or the like from the similarity of each part of the face performed in the above manner. Here, the weight of each region can be determined based on its importance in human perception.

In the present invention, the integrated control server extracts a face of a person from a photographed image, extracts the outline of the face through a facial recognition program, encrypts the coordinates of the outline with a percentage based on the distance (1) To the internal main server.

Assuming that the coordinate distance 2 of the ear line is 80 (%) and the coordinate distance of the lip 3 is 150 (%) based on the distance 1 between the pupils 100 (%) In case of encrypting only three coordinates, the encryption code to be transmitted to the main server in the integrated security center is "100.80.150", which enables double encryption.

In other words, by extracting facial information from facial recognition program on Fuzzy Qingyuan, only the code with encrypted code is sent to minimize the problem of privacy infringement. Also, facial contour coordinates of wanted criminals and sex offenders are numerically expressed as a percentage Improving the performance of school zone CCTV surveillance system, featuring an event step that pops up an event on the integrated crime prevention center monitor when a match with a cryptographic code and an encryption code received from the integrated control server is matched with a wanted criminal or a sex offender Method.
