    1443 Words  | 6 Pages

    Fingerprint recognition refers to the automated process of verifying a match between human fingerprints. Fingerprints are one of the types of biometrics used for identifying individuals and verify their identity. The analysis and study of fingerprints for matching generally requires the comparison of several features of the fingerprint pattern. These include patterns, which are characteristics of ridges and minutia points, which are unique features found within the fingerprint patterns. It is

  • Optical Character Recognition (ALPR)

    1070 Words  | 5 Pages

    3.2. What is ALPR? Automatic license plate recognition (ALPR) is a mass surveillance method that uses optical character recognition (OCR) to automatically identify the license number plate in an image or video. By providing the OCR with the correct search criteria you need to train it. To train the OCR means to get enough positive and negative images of the object you want to identify. The training involves in to an Extensible Markup Language (XML) that can be used to identify die object in the image

  • Pros And Cons Of Face Recognition

    1716 Words  | 7 Pages

    Face recognition technology [1] is the least intrusive and fastest biometric technology. It works with the most obvious individual identifier – the human face. Instead of requiring people to place their hand on a reader (a process not acceptable in some cultures as well as being a source of illness transfer) or precisely position their eye in front of a scanner, face recognition systems unobtrusively take pictures of people 's faces as they enter a defined area. There is no intrusion or delay, and

  • How Has The Development Of Fingerprints Changed Over The Years

    548 Words  | 3 Pages

    Fingerprints have been scientifically studied for a number of years in our society. The characteristics of fingerprints were studied as early as the 1600s. Meanwhile, using fingerprints as a means of identification first transpired in the mid-1800s. Sir William Herschel, in 1859, discovered that fingerprints do not change over time and that each pattern is unique to an individual. With these findings, he was the first to implement a system using fingerprints and handprints to identify an individual

    traits that can be used to recognize people at a distance. Therefore, this trait is very appropriate in surveillance scenarios. Most gait recognition algorithms attempt to extract the human silhouette in order to derive the gait variables. Hence, the selection of a good model to represent the human body is pivotal to the efficient functioning of a gait recognition system. However, the gait of an individual is affected by footwear, clothing, affliction of the legs, or walking surface. Walking is a

  • Dna Fingerprinting Lab Report

    The lab focuses on DNA fingerprinting which is usually done in forensics to catch criminals by the analysis of DNA fragments of different sizes by a method called electrophoresis. Electrophoresis is a separation technique that uses an electric field to separate and distinguish biological molecules (this including DNA) in the experiment, gel is used to as a way to apply friction in electrophoresis which can help you easily distinguish between the DNA because of different sizes in the DNA confirmations

(The National Institute of Standards and Technology, 2013) Examples of pattern evidence include fingerprints, shoeprints, tire threads, firearms and bloodstains. Pattern analysis such as analysing of handwriting are also part of pattern evidence. The analysis of pattern evidence is a useful tool and has always been used in the field of forensic science
