application.
• Forms new connections between people and helps keep in
touch with existing friends.
• CM also provides the user: status, social updates ,check-ins
with duration , etc. of their friends on a map.
• Through CM, user will be able to digitize and efficiently store
huge collection of personal and official visiting cards.
• The application further provides the functionality of
automatically updating the users’ contact info to all friends
whenever a user makes a change in his/her contact info.

3. Scope of the Project
• The application will provide the user an ability to
scan, digitize and store the visiting cards. Upon which
the application asks the user whether to send a
personal friend request or not provided the contact
is already a user of this application. The application
allows the user to keep track of their friends’
activities through social networks and place a visual
marker on a map as to their location if he/she wishes
to share it.
• The application consists of two parts; client and
server.

4. Functional Requirements
• User Registration and Contact details
i. Store users’ information like name, phone numbers,
address, emails, etc.
ii. Set Username.
iii. Set Password.
iv. Ask for optional connectivity to third party social sites.
• Contact Info
i. Automatically update and display the latest contact
details of other users in user’s contact list.

5. Functional Requirements (Contd.)
Visiting Card Scanner
i. Pre Processing: Analyze the input image of a visiting card for text
regions and pass on those regions to OCR (Optical Character
Recognition).
ii. OCR: The OCR will automatically convert the text regions into
digital text format.
iii. Structural Analysis: Entities like names, address, phone no’s, are
found based on the natural language processing principles.
iv. Text Pre-Processing: Analyzing the input text for special constructs
of the language i.e. special treatment required for abbreviations,
acronyms, date, time, numbers, currency amounts, e-mail
addresses etc.

6. Functional Requirements (Contd.)
Visiting Card Scanner
v. Post Check: After storing the information one final check is to ask
the user for confirmation of the data that is read off the card by
the application.
vi. Categories: A contact can be placed in multiple classification groups
according to users’ choice like friends, family, co-workers, etc.
vii. Contact Information Storage: After the analysis of the extracted
text the information is divided into parts and stored in its proper
place.
viii. Friend request: Based upon the contact number, a friend request
would be sent to that person, provided the details belong to an
existing user of ConnectMe.

7. Functional Requirements (Contd.)
• Social Center
• Friend finder: Place visual markers on a map for the
last know location of a friend based upon a GPS
network or the last check-in only if that friend wishes
to share location details.
• Share My Location: Allows the user to share his/her
current location based upon GPS coordinates.
• Monitor Friends’ Activities:
This functionality allows a user to:
» Check if any friends are in the vicinity (a certain radial
distance from the user’s location is considered) and
contact them.
» Retrieve latest activities of friends from their social
networks.
