Gait Recognition is an Biometric Feature which has attracted many researchers in recent years. Gait recognition is a task to identify or verify individuals by the way they walk. In Video Surveillance based application identifying the Human gait is important because it captures the human from a distance[1]. Gait Recognition have advantages like Unobtrusiveness, other is that without knowledge of a person his gait can be captured and also high quality of videos are not required. Gait Recognition approaches are divided into two types : Model Free and Model based Approaches[2]. Model based approaches have a series of static or Dynamic body parameters by tracking body components such as limbs, legs, arms and thighs, Gait signatures derived from …show more content…

Recognition: Extracted samples are compared to the samples stored in a database. The identity of an individual having the most (and enough) similar gait sample is picked and stated as the recognition verdict. Gait recognition system can be used in a number of scenarios. If an individual walks by the camera who’s gait has been previously recorded and he is stated as a threat, then the system will identify him and the concerned authorities can be automatically alerted. Such systems have a large amount of strong application in airports, banks or other high security areas. METHODS FOR GAIT RECOGNITION [4] Principal component analysis (PCA) is applied to reduce the dimensionality . Dynamic time warping is used to differentiate the different gaits of human. This reduction obtained by PCA is important to make classification with DTW more efficient and save computing time to meet the requirements of real-time applications. PCA (Principal Component Analysis) : PCA is the simplest method of the True Eigenvector-based multivariate …show more content…

In order to enhance the class separability further and avoid the potential overfitting, a discriminative locality preserving projection with sparse regularization is used to transform the refined tensor data to the final vector feature representation for recognition. An efficient tensor to vector projection algorithm is introduced to find a low-dimensional tensor subspace of the original input gait sequence

Figure 9.4 – Stream When the stream starts, OpenCV, which is running on the server, starts detecting and recognizing faces and displaying the results in a list that resides on the right sidebar. A green box appears, containing the information and the image of the recognized face. If the detected face is unrecognized, a red box appears, containing the face of the unknown individual. Figure 9.5 – Detecting & Recognizing Faces Right after an unrecognized face is caught, an email is sent as an alert for the security guards, containing the unrecognized face of the individual, alongside the date, the time and the IP Camera’s information.

Multilinear principal component analysis (MPCA) is a mathematical procedure that uses multiple orthogonal transformations to convert a set of multidimensional objects into another set of multidimensional objects of lower dimensions. There is one orthogonal (linear) transformation for each dimension (mode); hence multilinear. This transformation aims to capture as high a variance as possible, accounting for as much of the variability in the data as possible, subject to the constraint of mode-wise orthogonality. MPCA is a multilinear extension of principal component analysis (PCA).

The main character of the book Locomotion which is written by Jacqueline Woodson is about a boy whose parents were killed in a building fire when he was 7 years old. Lonnie and his little sister Lili were separated and put into a different foster home because the foster parent didn 't want to have a boy in her house. The conflict in the book is Lonnie 's struggle to find a way to live with what happened to his parents and his little sister not being with him.

In the novel, Song of Solomon, Toni Morrison develops the character Macon Dead, who acquired the nickname of Milkman. The actions of others can influence a life and the course of life for a person that has no real idea or firmness in decision making of their own. Milkman gets his nickname because he was breastfed by his mother at an oddly old age, and a man sees that through a window and begins laughing. While the name is is quite literal to the actual situation that made his acquire it such as being breast fed. Throughout the novel Milkman grows up rather advantaged and sheltered.

Dubbed the Valley Intruder or Night Stalker, Ricardo Leyva Munoz Ramirez famously known as Richard Ramirez, struck fear through the bones of many during his serial killing spree in the mid-eighties. Ramirez killed at least fourteen people in his spree while raping and torturing many more. His criminal beginnings turned to violence in June of 1984 with his first known slaying of 79-year-old Jennie Vincow. Vincow was sexually assaulted, stabbed and ultimately killed in her home. Authorities had not yet caught Ramirez after this brutal homicide, therefore he was free to continue his spree on countless more helpless victims.

I have never lived away from home before attending college, so at times I feel homesick for the luxuries my family home provided me with. For example, I greatly miss my cats, my sister, having a private kitchen and bathroom, access to a car, and our spacious backyard. I often cannot wait to go home as I know all these things await me. I even frequently complain about missing these aspects of my life. For the millions of people displaced across the globe the feelings I have are massively multiplied as they are not just away from their home for a few months, but instead forced to abandon their homes forever.

Everyday we encounter new and familiar faces. We are able to distinguish our mother’s face from a stranger’s face due to the facial recognition processes that we have stored in our brains. Facial recognition is one of the many processes of object-recognition. Many of us are not aware of the brain’s role in facial recognition because it is a process that we are not consciously doing. Face recognition differs from object recognition in a few ways.

The 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.
