Importance Of Recognition
involved in iris recognition process are given as follow. (i) Image acquisition- It interfaces between the real world and the system; it has to acquire all the necessary data. In this step, a high – quality image of an eye is captured. (ii) Iris segmentation and location- Sometimes necessary pre-processing has to be done to remove artifacts, to enhance (e.g. removing background noise) the image. Then locate the edge of the iris as well as pupil i.e. to extract the iris region. (iii) Normalization and unwrapping process- Extracted iris region is transformed into a fixed dimension in order to allow comparisons between different irises and then normalized iris region is unwrapped into a rectangular region. (iv) Feature extraction- Textural pattern are obtained from decomposed rectangular region so that a comparison between templates can be done. (v) Matching process- A decision is made by comparing obtained templates with the templates stored in database. 1.7 Importance of iris recognition …show more content…
Numerous of biometric identification technologies such as fingerprint recognition, face recognition, speech recognition and iris recognition come around to meet those demands but all of these technologies do not fulfill the all requirements and faces many problem. In face recognition, it itself is a 3D object that varies depending on the angle, pose, illumination, and age. For a picture taken a year ago, result may have error rate of 43% to 50% even after using the best current

657 Words | 3 PagesA conventional artwork and drawing can be converted into graphic by scanning into digital form. Graphic can be categorized into two types, Bitmap Graphic and Vector Graphic. Bitmap graphic is made up of many dots arranged in matrix and specific order while Vector graphic is stored as a mathematical formula. Thus, Bitmap graphic does not require special software to read because no processing is require before displaying it. However, due to this reason, it occupies more space compared to Vector graphic and take longer time to transfer over network.
The Pros And Cons Of Fingerprinting
1172 Words | 5 PagesFingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).
Why Respect Is Important

Hearing what your client needs from you and trusting that they know their story best shows that you are listening and engaged, along with eye contact, verbal or visual confirmations that you are hearing them is also important. Being heard and feeling like your important can be more help than the actual help itself.
Biometric Unlocking Essay
898 Words | 4 PagesThe authentication of Biometrics (i.e. the real authentication) which is used for identification and controlling the access which can be applied in the computer science. It is can be used in groups to identify the individuals under the surveillance. Biometric identifiers are used to labels the characteristics which can be measurable, the distinctive, and to describe the individuals. Biometric identifiers are being often categorized as behavioral versus physiological characteristics. Physiological are related to define the characteristics and the structure of the body.
Essay On Face Recognition
2057 Words | 9 PagesOn the complement, face identification is a 1: N problem. It is used compares a query face image against all image templates in a face database. Face recognition has distinct advantages over biometrics systems using finger print/palm print and iris, because of its non-contact process. It is mainly used in security systems. Face images can be captured from a distance without touching the person and the identification does not require interacting with the person.

The Criminal Justice System: The Evolution Of Fingerprinting
250 Words | 1 PagesBackground Ancient archeological artifacts and historical items have been discovered to still retain a large number of fingerprints on them. Since this was discovered significant strides in fingerprinting and identification have been made. In 1788 a detailed description of anatomical formations of fingerprints was made. Then in 1823 fingerprints began to be classified into nine categories, and by the 19 the century Sir Francis Galton had developed analytical methods for fingerprint matching. As the criminal justice system evolved, there arose the need for criminals to be uniquely identified by some physically identifiable trait.
Advantages And Disadvantages Of Being Biometric
1502 Words | 7 PagesBiometric refers to the way by which an individual can be identified according to their unique biological traits. Considering the fact that each individual is unique, a person can easily be identified by his or her inborn physical or behavioral traits. Hence, making it easier to identify a person under surveillance or someone who has just committed a crime. There are several ways by which a person can be biometrically indentified, the oldest of them being the ‘fingerprinting verification’. Since then, it is fair to say that biometric has undergone a considerable evolution with the advent of computerized databases and the digitization
DNA Fingerprinting Analysis In Forensics
1724 Words | 7 PagesFor an analyst to match the specific print, they will use the ridge characteristics to identify specific points on a suspect fingerprint which the same information in a known fingerprint already in the database (Koehler, 1991). For example, if an analyst were to compare a fingerprint from a crime scene to a fingerprint already in the database, they would first have to collect known prints with the same general pattern type. Next, the analyst would use a loupe to compare the fingerprints side by side to identify certain information within the details that match. If enough minutiae correlate, the fingerprints are then determined to be from the same
Why Informants Is Important
1148 Words | 5 PagesPolice officers have used informants for several different reasons over the years. This tactic has been in practice for many years now with mixed results. Informants can either be an asset or hindrance depending on the situations that unfold during the investigation. Over time we have seen that for the most part using informants can be useful and can help make a case, but we have also seen the down-side where it has made the case fall completely apart in a vicious turn that the officers did not want to happen. In this paper I plan to cover the topics of: the use of informants, the down-side of using informants, how officers can misuse informants, and the benefits of informants.

Wrinkles play an essential role in the face-based analysis. They have been widely used in applications, such as face age estimation, facial retouching and facial expression recognition. Facial wrinkles are 3D features of skin and appear as skillful discontinuities or cracks in surrounding skin texture.
