Automated Door Operation System Using Face Recognition

1.Aim

To prepare a well explained conceptualization of an automated door operation system by incorporating

certain extended systems like Lighting Control, Security System and Automated Attendance for specific

occupancy purposes.

2. Introduction

2.1. What is Face recognition system?

Afacial recognition system

is a computer application automaticallyidentifying orverifying aperson from

adigital image or avideo frame from avideo source. One of the ways to do this is by comparing selectedfacial

features from the image and a facialdatabase.It is typically used insecurity systems and can be compared to

otherbiometrics such asfingerprint or eyeiris recognition systems.

2.2. What is its significance?

Among the different biometric techniques, facial recognition may not be the most reliable and

efficient. However, one key advantage is that it does not require the cooperation of the test subject to work.

Properly designed systems installed in airports, multiplexes, and other public places can identify individuals

among the crowd, without passers-by even being aware of the system. Other biometrics like fingerprints, iris

scans, and speech recognition cannot perform this kind of mass identification.

Facial recognition systems based on faceprints can quickly and accurately identify target individuals

when the conditions are favorable. However, if the subjects face is partially obscured or in profile rather thanfacing forward, or if the light is insufficient, the software is less reliable. Nevertheless, the technology is evolving

quickly and there are several emerging approaches, such as 3D modeling, that may overcome current problems

with the systems. According to the National Institute of Standards and Technology (NIST), the incidence of false

positives in facial recognition systems has been halved every two years since 1993 and, as of the end of 2011,

was just 0.003%

Law enforcement agencies are using facial recognition software as a crime-fighting tool. Facial

recognition software also enhances marketingpersonalization.Now businesses are looking to use the

technology to reach customers. For example, billboards have been developed with integrated software that

identifies the gender, ethnicity and approximate age of passersby to deliver targeted advertising.

2.3.

What are the different applications with regard to security?

The security currently become a very important issue in public or private institutions in which various

security systems have been proposed and developed for some crucial processes such as person identifications,

verification or recognition especially for building access control, suspect identifications by the police, driver

licenses and many others. Face recognition technology has seen many uses in governments, military forces,

banks, social welfare and security, electronic commerce and security and defence fields. Various uses of face

recognition system in doors is discussed here.

Domestic Use

Face recognition system can be used as a security system for houses and residential buildings.

Specifically when a person tries to access the door it either allows the person through the door if the person is

an authorized user or it specifies the owner of the house regarding the use of the door by any anonymous

person. In some cases when the user tries to access the door by forcible means it activates an alarm so that the

neighbours or the security of house can respond.

Offices

Face recognition system has many uses in offices.

It can be used for saving important files and documents which can be used only by a specified personal.

It can be used for allowing only the staff and other people who were pre-specified in the database of the

face recognition system.

It can act as an automated security system during free hours of the office usually when the office is

vacant.

Banks

The main use of face recognition system in banks is to have protected lockers for saving money and

important documents of properties.

Military

Military of many nations use face recognition system as an additional security system for the access of

highly valuable, precarious, dangerous and sophisticated weapons and armaments. These systems not onlyimprove the security of individual buildings but also increases the security of the state and country as a whole.

2.4.

What are the disadvantages?

Many citizens express concern that theirprivacy is being compromised by the use of surveillance

technologies by corporations and the state. Some fear that it could lead to a totalsurveillance society, with

the government and other authorities having the ability to know the whereabouts and activities of all citizens

around the clock. This knowledge has been, is being, and could continue to be deployed to prevent the lawful

exercise of rights of citizens to criticize those in office, specific government policies or corporate practices.Many centralized power structures with such surveillance capabilities have abused their privileged access to

maintain control of the political and economic apparatus, and to curtail populist reforms.

Facial recognition can be used not just to identify an individual, but also to unearth other personal data

associated with an individual such as other photos featuring the individual, blog posts, social networking

profiles, Internet behavior, travel patterns, etc. all through facial features alone. Moreover, individuals have

limited ability to avoid or thwart facial recognition tracking unless they hide their faces. This fundamentally

changes the dynamic of day-to-day privacy by enabling any marketer, government agency, or random stranger

to secretly collect the identities and associated personal information of any individual captured by the facial

recognition system.

Whatever might the propensity of disadvantages be in other fields, the face recognition system in the

security applications has been found very instrumental in automating the security operations in various walks of

industrial and domestic fields.

2.5. How does the FR Software work?

Object detection and tracking are important in many computer vision applications including activity

recognition, automotive safety, and surveillance. In this example, you will develop a simple face tracking system

by dividing the tracking problem into three separate problems:

1. Detect a face to track

2. Identify facial features to track

3. Track the face

Step 1: Detect a Face To Track

Before you begin tracking a face, you need to first detect it. Use the vision.CascadeObjectDetector to

detect the location of a face in a video frame. The cascade object detector uses the Viola-Jones detection

algorithm and a trained classification model for detection. By default, the detector is configured to detect faces,

but it can be configured for other object types.

% Cr eat e a cascade det ect or obj ect . f aceDet ect or = vi si on. CascadeObj ect Det ect or ( ) ;

% Read a vi deo f r ame and r un t he det ect or . vi deoFi l eReader = vi si on. Vi deoFi l eReader ( ' vi s i onf ace. avi ' ) ;vi deoFr ame = st ep( vi deoFi l eReader) ;bbox = st ep( f aceDetector , vi deoFrame) ;

% Dr aw t he r et urned boundi ng box ar ound t he det ect ed f ace. vi deoOut = i nser t Obj ect Annotat i on( vi deoFr ame, ' r ectangl e' , bbox, ' Face' ) ;f i gur e, i mshow( vi deoOut ) , t i t l e( ' Det ect ed f ace' ) ;

You can use the cascade object detector to track a face across successive video frames. However, when

the face tilts or the person turns their head, you may lose tracking. This limitation is due to the type of trainedclassification model used for detection. To avoid this issue, and because performing face detection for every

video frame is computationally intensive, this example uses a simple facial feature for tracking.

Step 2: Identify Facial Features To Track

Once the face is located in the video, the next step is to identify a feature that will help you track the face. For

example, you can use the shape, texture, or color. Choose a feature that is unique to the object and remains

invariant even when the object moves.


6/14

In this example, you use skin tone as the feature to track. The skin tone provides a good deal of contrast

between the face and the background and does not change as the face rotates or moves.

% Get t he ski n tone i nf or mat i on by ext r act i ng the Hue f r om t he vi deo f r ame% conver t ed t o the HSV col or space.

Step 3: Track the Face

With the skin tone selected as the feature to track, you can now use the vision.HistogramBasedTracker

for tracking. The histogram based tracker uses the CAMShift algorithm, which provides the capability to track an

object using a histogram of pixel values. In this example, the Hue channel pixels are extracted from the nose

region of the detected face. These pixels are used to initialize the histogram for the tracker. The example tracks

the object over successive video frames using this histogram.

What happens inside the FRM?

The FRM used in the present installation works on Viola Jones Face Detection Algorithm for which the

steps are discussed at length along with the code in the previous section. The hardware part of the FRM works

in the following mechanism. The functions of all the components that constitute the FRM are clearly mentioned

in the flowchart. Many commercially available machines follow a similar process. One such machine we

referenced for learning the mechanism is HF-FR701 which is a product by Chongquing Huifan Technology Co.,

Ltd.

Door opening and closing

1.

The occupancy sensor which is door mounted, detects the person and sends a binary signal to the

FRM

2. The FRM activates the High Resolution Infrared Camera and the digital output of the face ID is

generated.

3.

The FRM uses TCP/IP protocol for communication and uses the RS 232 cable for data transfer.

4.

There is an intermediate RS232/485 converter placed to convert the RS232 signals to RS485

5. Later this information is sent to the PC(Router) via RS 485 cables.

6.

Every Router has an unique IP address and is connected to the HUB via CAT5 cables

8. If the persons face ID matches with the authorized, the FRM sends a binary signal to the

Electromagnetic lock and it opens.

9.

If the persons face ID does not match with the authorized, the FRM sends a binary signal to the

security alarm and the security personnel of the building is cautioned.

10.

After a person has moved in, the occupancy sensor sends a binary signal to the FRM and the

Electromagnetic Lock is actuated and the door is locked.

11.

If the person wants to exit from the room, he presses the EXIT button which is wall mounted.

12.

When the EXIT button is pressed a binary voltage signal is sent to the FRM, the ElectromagneticLock is actuated and the door opens.

13.After the person has moved out, the occupancy sensor again sends a binary signal to the FRM, and

the Electromagnetic Lock is actuated and the door is locked.

3.2.

Lighting System

The Face Recognition mechanism can be used for controlling the lighting inside the room and hence

it can help in energy saving.

1.

When an authorized face ID is recognized, the occupancy of the room is increased by one.

2.

Similarly when a person presses the EXIT button, the occupancy of the room is deducted by one

3. So whenever the occupancy of the room is zero, the FRM sends a binary signal to the lighting

system and the lights are turned off.

3.3.

BACNET Network

In a commercial building there can be multiple installations of the face recognition system.

The BACNET network is used for connecting all the routers, controllers , sensors and actuators to

a common HUB.

Each PC (Router)has a unique IP address

The FRMs(Controllers) have a unique Net ID

The sensors have a unique Instance ID

TCP/IP

TCP/IP communication mode is used between the hub and the computer that checks the ID

created by the FR 701 and sees if it matches with the pre-existing database of IDs. TCP/IP provides end-to-end

connectivity specifying how data should be formatted, addressed, transmitted,routed and received at thedestination. This utilizes Cat5 cables.

6.Algorithms for various connections

6.1.

Occupancy Sensor to Lighting System : ( Communication : Binary Output )

1. Initialize occupancy =0

2. If Sensor = 1 => occupancy=occupancy+1

3.

If Exit= 1 =>occupancy= occupancy -1 (When the exit switch is pressed from inside the room)

4. If (occupancy >1 ) Turn on the lights else Turn off the lights

6.2.

FRM to EM lock : ( Communication : Analog)

1. The FRM recognizes the face and generates a face id

2. Matches the face id with the database

3. If the face id matches with the authorized then the lock opens

4. If the face id does not match with the authorized , lock does not open and the information is

sent to the security system
http://en.wikipedia.org/wiki/Routinghttp://en.wikipedia.org/wiki/Routing


12/14

6.3. FRM to Electronic Bell : (Communication : Analog)

1. If the face id does not match with the database a binary signal is sent to the electronic bell

2.

The electronic bell is turned on.

6.4. PC to HUB

1. The PC is connected to the HUB using CAT 5 cables.

2. The PC uses TCP/IP protocol to communicate with the hub

3. The hub hosts the information of all the valid ids

4.

This connection is used to check the validity of an incoming id

6.5. FRM to PC

1. The Controller generates a digital output of the face id

2. These signals are transmitted via RS 232 cables

3. As the PC uses RS 485 input, a RS232/485 converter is used to convert the RS232 signals to RS

485

(A PC can use both RS 232 and RS 485 communication but RS 485 communication is preferred

as many controllers can be connected to the PC)

6.6. Occupancy Sensor to FRM

1.

The occupancy sensor generates a binary output (0- no occupancy & 1- occupancy)2. If occupancy=1 then the FRM actuates the IP camera

3. The IP camera starts reading the face of the person

6.7.

Exit Button to FRM(Communication: Binary)

1. When a person presses the exit button from inside, a binary signal is generated and it is sent to

FRM (Exit=1)2.

The FRM recognizes the signal and actuates the Electromagnetic Lock3.

And also the occupancy measure of the room is reduced by 1 (Occupancy=Occupancy-1)6.8.

Automated Attendance System

This system can be used for a board room or a meeting room to maintain a directory for theattendance

1. The FRM recognizes the face and generates the face id.
