US award for AQI app

Indian students win US award for AQI app, November 6, 2018: The Times of India

Three students of Bharti Vidyapeeth College of Engineering in Delhi have developed an Android app to measure the alarming pollution levels in the National Capital Region (NCR), the US-based Marconi Society, which awarded them with a prize, said.

“The three students of Bharti Vidyapeeth have developed the application using smartphone camera images to measure the Air Quality Index (AQI) in NCR, especially Delhi, by anyone with a smartphone,” said the Society.

The undergraduate engineering students are Tanmay Srivastava, Kanishk Jeet and Prerna Khanna, who jointly won the cash prize of $1500 (Rs 1,09,500) last week in a contest, organised in India and sponsored by the Society under its Celestini Programme.

NCR, especially Delhi, has been in the grip of toxic air for a week, mainly due to thick smoke emanating from the burning of stubble in the farmlands of Haryana and Punjab and lakhs of automobiles emitting fossil fumes.

“The three have developed “air cognizer”, a portable, real-time air quality analytics application, which is available at Google Play store to download freely by any smartphone user to measure the air quality in his/her area,” said the Society. “The user has to upload an image taken outdoor with half of it covering the sky. Using image processing techniques, features are extracted and the machine learningmodel of the app estimates the AQI in the area,” said the statement.

The model is deployed on smartphones using Tensorflow Lite and ML Kit from Google, the world’s largest search engine behemoth.
