Бугунги кунда хавфсизлик тизимларида биометрикадан фойдаланиш оммалашиб бормоқда. Биометрикага асосланган тизимлар ҳар бир инсонни анатомик ўзига хослигига асосланади. Анатомик белгиларга юз, кўз қорачиғи, бармоқ излари, кафт каби биометрик белгилар киради. Юзни аниқлаш тизим самарадорлиги юздаги белгиларни ажратиб олиш самарадорлигига бевосита боғлиқ. Юз тасвири асосида шахсни таниб олиш одатда локал ва глобал белгилар асосида амалга оширилади. Локал белгиларни шакллантиришда юз тасвири алоҳида қисмларга ажратилади ва шакллантирилган локал белгилар асосида таниб олиш амалга оширади. Глобал белгиларни ажратиш эса бутун юз тасвирида белгиларни шакллантиришдан иборат бўлиб, улардан информативларини ажратиш орқали таниб олиш харажатларини камайтириш мумкин.Мазкур мақола юз тасвири информатив белгилар фазосини шакллантириш алгоритмларини таҳлилига бағишланган бўлиб, унда информатив белгиларни аниқлаш процедураси баён этилган бўлиб, юз тасвири информатив белгиларини ажратиш усул ва алгоритми таклиф этилган

Today, the use of biometrics in security systems is becoming popular. Biometrics-based systems are based on the anatomical uniqueness of each person. Anatomical features include biometric features such as face, pupil, fingerprint, and palm. The performance of the face recognition system is directly related to the performance of face feature extraction. Facial recognition is usually based on local and global features. In the formation of local features, the face image is divided into separate parts, and recognition is performed based on the formed local features. Global feature extraction is the formation of features in the entire face image, and the cost of recognition can be reduced by separating the informative ones from them.In this article, the algorithms for creating the informative feature space for faces are analyzed, the process for locating informative features is explained, and a technique and algorithm for differentiating between face image informative features are suggested
