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.
Face recognition technology may help solve problems with identity verification by analyzing facial features instead of passwords or pins. The document outlines the key stages of face recognition systems including data acquisition, input processing, and image classification. It also discusses advantages like convenience and ease of use, as well as limitations such as an inability to distinguish identical twins. Potential applications are identified in government, security, and commercial sectors.
This document discusses biometrics and face recognition technology. It defines biometrics as unique human characteristics that can be used to identify individuals, including physiological traits like fingerprints and behavioral traits like signatures. Face recognition systems work by detecting faces, aligning and normalizing images, extracting nodal point measurements, and comparing new images to stored templates. The software searches video for faces, determines positioning, scales images, and translates facial data into codes for comparison. Face recognition provides convenient identity verification for applications like security, access control, and banking. However, it cannot distinguish identical twins and some view it as an invasion of privacy.
A facial recognition system is a technology capable of identifying or verifying a person from a digital image or a video frame from a video source.

Elasticity vs. State? Exploring Kafka Streams Cassandra State StoreScyllaDB
kafka-streams-cassandra-state-store' is a drop-in Kafka Streams State Store implementation that persists data to Apache Cassandra.
By moving the state to an external datastore the stateful streams app (from a deployment point of view) effectively becomes stateless. This greatly improves elasticity and allows for fluent CI/CD (rolling upgrades, security patching, pod eviction, ...).
It also can also help to reduce failure recovery and rebalancing downtimes, with demos showing sporty 100ms rebalancing downtimes for your stateful Kafka Streams application, no matter the size of the application’s state.
As a bonus accessing Cassandra State Stores via 'Interactive Queries' (e.g. exposing via REST API) is simple and efficient since there's no need for an RPC layer proxying and fanning out requests to all instances of your streams application.

4. Introduction
The information age is quickly revolutionizing the way transactions are
completed. Everyday actions are increasingly being handled
electronically, instead of with pencil and paper or face to face. This
growth in electronic transactions has resulted in a greater demand for
fast and accurate user identification and authentication. Access codes
for buildings, banks accounts and computer systems often use PIN's
for identification and security clearances.
Using the proper PIN gains access, but the user of the PIN is not
verified. When credit and ATM cards are lost or stolen, an unauthorized
user can often come up with the correct personal codes. Despite
warning, many people continue to choose easily guessed PIN‟s and
passwords: birthdays, phone numbers and social security numbers.
Recent cases of identity theft have heighten the need for methods to
prove that someone is truly who he/she claims to be.
Face recognition technology may solve this problem since a face is
undeniably connected to its owner expect in the case of identical twins.
Its nontransferable. The system can then compare scans to records
stored in a central or local database or even on a smart card.
5. A biometric is a unique, measurable characteristic of a human being
that can be used to automatically recognize an individual or verify
an individual‟ s identity. Biometrics can measure both physiological
and behavioral characteristics. Physiological biometrics (based on
measurements and data derived from direct measurement of a part
of the human body) include:
a. Finger-scan
b. Facial Recognition
c. Iris-scan
d. Retina-scan
e. Hand-scan
What are
Biometrics ?
6. Modern Portfolio
Presentation
Face recognition is a method
of identifying or verifying the
identity of an individual using
their face. Face recognition
systems can be used to
identify people in photos,
video, or in real-time.
What is
Face Recognition?
7. ?
It can use your existing
hardware infrastructure,
existing camaras and image
capture.
It is the only biometric that
allow you to perform passive
identification in a one to. Many
environments
Overall it is the most efficient
system to collect automatic
student attendance of Online
class in Corona Pandemic
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.
8. For face recognition there are two
types of comparisons.
Classification of
FACE
RECOGNITION
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. All identification or authentication technologies operate
using the following four stages:
1) Capture: A physical or behavioural sample is
captured by the system during Enrollment and
also in identification or verification process.
2) Extraction: Unique data is extracted from the
sample and a template is created.
3) Comparison: The template is then compared
with a new sample.
4) Match/non match: The system decides if the
features extracted from the new Samples are a
match or a non match
10. 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.
Some facial recognition approaches use the whole
face while others concentrate on facial components
and/ or regions (such as lips, eyes etc). The
appearance of the face can change considerably
during speech and due to facial expressions.
The input can be recorded video of the speaker
or a still image. A sample of 1 sec duration
consists of a 25 frame video sequence. More
than one camera can be used to produce a 3D
representation of the face and to protect
against the usage of photographs to gain
unauthorized access.
Synergetic computer are used to
classify optical and audio
features, respectively. A
synergetic computer is a set of
algorithm that simulate
synergetic phenomena. In training
phase the BIOID creates a
prototype called face print for
each person. A newly recorded
pattern is pre-processed and
compared with each face print
stored in the database. As
comparisons are made, the
system assigns a value to the
comparison using a scale of one
to ten. If a score is above a
predetermined threshold, a match
is declared.
Three
Stages
Implementation of Face Recognition Technology
11. How Face Recognition Systems
Work
If we look at the mirror, we can see that our 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.
There are about “80 nodal points” on a human face.
Here are few nodal points that are measured by the
software.
• distance between the eyes
• width of the nose
• depth of the eye socket
• cheekbones
• jaw line
• chin
13. Face Bunch Graph
A Face bunch graph is created from “70 nodal
points” to obtain a general representation of face.
Given an image the face is matched to the Face
bunch graph to find the same point.
These nodal points are measured to create a
numerical code, a string of numbers that represents
a face in the database. This code is called face
print.
Only 14 to 22 nodal points are needed for face it
software to complete the recognition process.
14. Face Recognition Attendance System
The modern face recognition attendance system is
much efficient and safer than the conventional
counterparts. There are a few attendance systems
that are based on the face recognition technology
and each of them has extremely varying features for
the best suitability in different environments.
It provides a facility for the central data
management system.
A very cost effective method of recording the
attendance.
