Face recognition is a biometric technique that uses unique facial measurements to identify or verify individuals in images. It analyzes the shape, pattern, and positioning of facial features. Face recognition systems first detect faces in images, then extract distinguishing nodal points like eye depth, nose width, and distance between eyes. They compare these measurements to templates stored in a database to identify matches. While convenient and non-invasive, face recognition has limitations like inability to distinguish identical twins and decreased accuracy with changes in appearance. It finds applications in security, law enforcement, and commercial uses like building access control and ATMs.

This slide is all about a detailed description of the Face Recognition System.
Humans often use faces to recognize individuals, and advancements in computing capability over the past few decades now enable similar recognitions automatically. Early facial recognition algorithms used simple geometric models, but the recognition process has now matured into a science of sophisticated mathematical representations and matching processes. Major advancements and initiatives in the past 10 to 15 years have propelled facial recognition technology into the spotlight. Facial recognition can be used for both verification and identification.
This application was design with help of OpenCv and C#.
Facial recognition (or face recognition) is a type of bio-metric application that can identify a specific individual in a digital image by analysing and comparing patterns.
Face recognition software is based on the ability to first recognize faces, which is a technological feat in itself. If we look at the mirror, we can see that your face has certain distinguishable landmarks. These are the peaks and valleys that make up the different facial features.
This application take picture of your face and after storing it.
Then it start identifying all face which are store in database.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

3. Introduction
In today's networked world, the need to maintain the security of
information or physical property is becoming both increasingly important
and increasingly difficult.
Face recognition is one of the few biometric methods that possess the
merits of high accuracy.
Complex and largely software based technique
Analyze unique shape, pattern &positioning of facial features
It compare scans to records stored in central or local database or even on a
smart card.
4. What is Biometrics ?
It is a unique measurable characteristics of a human being used to
automatically recognize an individual’s identity.
Two types
1.physiological
2. behavioral characteristics
A “biometric system” refers to integrated hardware and software used to
conduct biometric identification
5. Why we choose face recognition over other
biometric ?
• It requires no physical interaction on behalf of the user.
• It is accurate and allows for high enrolment and verification rates.
• It does not require an expert to interpret the comparison result.
• It can use your existing hardware infrastructure ,existing cameras and
image capture devices will work with no problems.
• It is the only biometric that allow you to perform passive identification in a
one to many environments (Eg. Identifying a terrorists in a busy Airport
terminal)
6. Face Recognition
• The Face – unique part .
• For face recognition there are two types of comparisons.
1 . Verification
This is where the system compares the given individual with who that
individual says they are and gives a yes or no decision.
2. Identification
This is where the system compares the given individual to all the other
individuals in the database and gives a ranked list of matches .

9. Data acquisition
• The input can be recorded video of the real or still image. A
sample of 1 sec duration consists of a 25 frame image
sequence. More than one camera can be used to produce a
3D representation of the face .
Input processing
• A pre – processing module locates the eye position and
takes care of the surrounding lighting condition and color
variance. First the presence of faces or face in a scene must
be detected . Once the face is detected ,it must be localized.
Face image classification
• Synergetic computer is used to classify optical and audio
features, respectively .A synergetic computer is a set of
algorithm that simulate synergetic phenomena.
10. 1.If you look at the mirror ,you can see that your face has certain
distinguishable landmarks. These are the peaks and valleys that make up
the different facial features. Software defines these landmarks as nodal
points .
2.There are about ’80 nodal points ’ on a human face .
3.Here are few nodal points that are measured by the software .
Depth of the eye

How Face Recognition Systems Work
12. Advantages
• Convenient, social acceptability
• More user friendly
• Inexpensive technique of
identification
Disadvantages
• Problem with false rejection when
people change their hair style,
grow or shave a beard or wear
glasses.
• Face recognition systems can’t tell
the difference between identical
twins
13. Applications
1 . Government Use:
a. Law Enforcement :Minimizing victim trauma verifying identify for
court records ,and comparing school surveillance camera images to know
child molesters .
b. Security/Counter terrorism :Access control ,comparing surveillance
images to know terrorist.
c. Immigration : Rapid progression through customs.
d. Voter verification : Where eligible politicians are required to verify
their identity during a voting process this is intended to stop ‘ proxy ’
voting where the vote may not go as expected.
14. 2. Commercial Use :
a. Residential Security : Alert home owners of approaching personnel .
b. Banking using ATM :The software is able to quickly verify a customer’s
face.
c. Physical access control of building areas ,doors , cars or net access .
15. Conclusion
• Face recognition technologies have been associated generally with very
costly top secure applications. Today the core technologies have evolved
and the cost of equipment is going down dramatically due to the
integration and the increasing processing power . Certain applications of
face recognition technology are now cost effective , reliable and highly
accurate .As a result there are no technological or financial barriers for
stepping from the pilot project to widespread deployment .
