AGENDA

• IoT Background• Purpose of our application• Application Process flow• Cloud Services used• Cloud Services Explained

IoT (Internet of Things)

• The Internet of Things (IoT) refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other Internet-enabled devices and systems.

Purpose/Idea of Our IoT Application

1. User attends an appointment in a building to meet his host for a meeting.

2. Our standalone application at the host building verifies the visitor’s identity and validates the meeting schedule.

3. Our smart phone application will aid indoor navigation.

Application Process Flow

FacePlusPlus

• Free cloud service that offers Face detection, Face analysis and recognition features.

• Supports cross platforms• Fast and accurate functions of face detection

from both images and videos.• Compares two given images and returns the

similarity index

• Input: REST URL• Output : JSON Response

How it works

Core Concepts

• Face++ API has 5 core classes of objects:• Image – The input image that is passed via a URL

parameter or HTTP POST• Face – Face detected within an image.Has unique

face_id• Person – Face collection of the same person• Faceset – Face collection, not necessarily of the same

person• Group – Set of persons. Used as a search pool to

identify a person

To use Face++ API• Sign up at Face++ Developer center• Create an application and get the API KEY

and API SECRET • Download the ‘Faceappsdk’ for the

preferred language• Include the SDK in the application• Access the services through the methodsprovided.

Methods Used

/detection/detect• Detects a face within a given image and

returns various attributes of the face.Parameters:• API Key• API Secret• Image

/recognition/compare• Computes the similarity between 2 faces • Parameters:Api_key,Api_secret,Face_id1,Fa

ce_id2

Abbyy Cloud OCR• Sent as a http POST method along with

authentication details, image and the output file name.

Eg: http://cloud.ocrsdk.com/processImage?language=English,Russian&profile=DocumentConversion&imageSource=Auto

Abbyy Cloud OCR

• Input : Scanned Image of the visitor’s drivers license

• Output: Text file with the extracted information

• Methods used: – submitImage, processDocument

Google Text-to-Speech

• Allows to hear English text spoken by a computerized voice.

• Generates pronunciations of whatever text is entered the end of this URL:

http://translate.google.com/translate_tts?tl=en&q=text

• Produces a mp3 file with the audio

Using the service

• Embed the .mp3 file in HTML’s audio tag<div style="display:none“><video controls="" autoplay="" name="media"><source

src="http://translate.google.com/translate_tts?tl=en&amp;q=What is your name?" type="audio/mpeg"></video>

</div>

Google Calendar API
