Aithal*2 # Research Scholar, College of Computer and Information Science, Srinivas University, Mangaluru-575001, Karnataka, India * College of Computer and Information Science, Srinivas University, Mangaluru-575001, Karnataka, India E-mail: karanikrishna@gmail.com ABSTRACT In Automatic Fingerprint Identification System (AFIS), preprocessing of the image is crucial process in deciding the quality and performance of system. Preprocessing is consists many stages as Segmentation, Enhancement, Binarisation, and Thinning. In these segmentation is one of the steps of preprocessing which differentiates foreground and background region of fingerprint …show more content…
There is enough amount of literature with respect to image segmentation process or approach dating back over thirty years. Jain & Dubes, (1988) [15], explains algorithm for clustering in his book, these early approaches for clustering can be used for segmentation, which acts as basis for many new methods including boundary based segmentation such as Canny edge detection Canny, 1986 [16]. In this method researcher defines comprehensive set of goals for the computation of edge detection points. Adams and Bishof, (1994) [17], proposed segmentation algorithm for images, which are intensity images with certain characteristics like robust, rapid, and free of tuning parameters. This algorithm can take input as either individual pixels or regions and points these inputs to some region formed by the algorithm. The algorithms explains two methods in which input corresponds to region, either by using manual seed or by automated procedure. Chakraborty et al., (1996) [18], proposed a method which combines region based segmentation and boundary finding to form new method which is more robust to noise and high performance. The literature covered above is some general segmentation algorithms which will apply for any types of images. In literature there are many studies available, which mainly focuses on fingerprint image …show more content…

Edge detection is widely used for detecting discontinuities in an image. Feature 7 is calculated in following way. The input face image is first converted
How did the FBI start and who was the man in charge of it all? J. Edgar Hoover was the head director of the FBI in 1924 to 2972 on his dying day. Hoover was raised by his mother and father in Washington D.C. He did not receive a birth certificate till he was 43 years old. His first job was running mail for the library of congress which he got at the age of 18.
Fingerprint is standard procedure when getting arrested or getting any sort of government jobs
Introduction During the investigation of who hit Reveille, 2 suspects (Bikerman and Maroon Flash) were inspected using gel electrophoresis to create a DNA fingerprint, fingerprint analysis, probable blood evidence analysis, and hair analysis. DNA Analysis In developing a DNA fingerprint using gel electrophoresis for Reveille’s, Bikerman’s, and Maroon Flash’s DNA, and DNA on Reveille’s fur, Bikerman’s shirt, and Maroon Flash’s shirt, the restriction enzyme fragment length polymorphisms were separated and the DNA evidence was compared to the known samples of Reveille’s, Bikerman’s, and Maroon Flash’s DNA. (This can be seen in the picture attached to this report of the gel electrophoresis.)
Scientific experts have been considered to provide impartial scientific evidence in contrast to most other types of evidence. But as illustrated by several examples like the misidentification of Brandon Mayfield in the Madrid Bomber case, it has been demonstrated that the forensic experts can be influenced by contextual bias. (Kassin, Dror & Kukucka, 2013) In Goodwin’s case there are several sources of error that due to a confirmation bias. The examiners were pre-armed with contextual information, they were aware that the target fingerprint belonged to an individual on the MI5 watch list, leading them to be suspicious of their target.
Rank the technologies by the level of effectiveness and reliability. In order by effectiveness and reliability from lowest to highest is electrostatic detection apparatus: which is a specialized piece of equipment used in questioned document examination. Then Automated Finger Identification System (AFIS): is a biometric identification methodology that uses digital imaging technology to obtain, store, and analyze fingerprint data as stated in ("What is Automated Fingerprint Identification System (AFIS)? - Definition from WhatIs.com," n.d.) and then the Portable light source: is a light that reveals fingerprints, blood, gunshot residue and more.
Molecular analysis is a well-known method and recently used by researchers. Using this

2.4 Band Division and Energy Computation: The power spectrum of the signal is multiplied by magnitude response of set of 33 triangular band pass filters and in the range 300Hz-2000Hz. Sub-bands are formed by using the logarithmic spacing. The positions of these filters are equally spaced along the Mel frequency, which is related to the common linear frequency f by following formula: Mel (f) = 1125* ln (1+f/700) (3) Mel frequency is proportional to the logarithm of linear frequency and which is close to the human perceptual system. 2.5 Sub Fingerprint Generation:
The Richard Ramirez "Night Stalker" case was one of the first major cases to use automated fingerprinting technology (Frese, 2011). Today, the fingerprinting database gives various probable identifications, then a trained fingerprint expert must compare the prints to find a likely identification. Considering that Ramirez's prints were found on the mirror of a stolen vehicle we can conclude that his fingerprints were two-dimensional, therefore the prints are termed as latent or residue prints. The authorities at the crime scene power-dusted his prints considering that is the best physical method for collecting fingerprints. Once analyzed using the ACE-V (analysis, comparison, evaluation and verification) method, the fingerprint expert was able to identify them as belonging to Ramirez.
People in the military are fingerprinted, and it is also required for many other occupations and organizations. When it comes time to match a fingerprint with an individual, it is quite easy due to the wide library of fingerprints the FBI maintains. This library contains the fingerprints of “more than 10%” of the U.S. population. For smaller cases, law enforcement are given access to this library directly from a police station ("Forensic Science" [Gale] 18).
Fingerprinting 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).
Biometric face recognition technology has received significant attention in the past several years to use human face as a key to security. Both law enforcement and non-law enforcement are its application. Face recognition system comprises of two Categories: verification and identification. Face Verification is Done in 1:1 match ratio. It is utilized to looks at a face pictures against a Template face pictures, whose identity being claimed.
These concept is also known as STP (Segmentation, Targeting
Has people's use of Photoshop gone too far? Is altering photos to make people unrealistically skinny a good idea? For years, many photos in magazines, advertisements, etc. have been altered, making models and celebrities blemish free and thin. But in some cases of retouched photos the outcome can be horrific, making the person very unprofessional and disturbing. But making models thinner than they actually are can have bad effects on the public.
