• Car License Plate Registration

    Car License Plate Registration

    Involvement as: Principal Investigator

    Synopsis: The objective is to propose an approach for automated car license plate detection and recognition. The system is expected to extract and process car license plate from frames of a video stream in real time (3 – 4 seconds) without the need of human intervention. The system is likely to be used for car access control where the detected license plate is supposed to be checked with an existing database. Detection s/w should work under following assumptions: 1) The video stream containing the relevant information (the view of the car with the front or rear license plate visible) is available. This further assumes that there is no control over the process of generation of this video stream. 2) The input to the proposed image recognition software system would be frames extracted from the above video streams. 3) For a given setup of capturing the video streams, the location of the license plate may be approximately known. This will help in discerning between other regions of the image frame that might contain alphanumeric characters.

  • Fingerprint Biometrics Platform Development

    Fingerprint Biometrics Platform Development

    Involvement as: Principal Investigator

    Synopsis: The Fingerprint Biometric platform is to be based on the TMS320VC5501 DSP from Texas Instrument. The hardware for this platform will be developed at Creative Solutions while the software is to be developed by DA-IICT for both verification and identification functions. It is assumed that the client has a database of maximum of 1000 registered users with registration of 3 fingerprints per user. Software should respond in not more than 1 sec. System may run as a standalone or as a node networked with a host computer having upto 256 similar nodes in the same network. Optical sensor may be used for data capturing. The whole system will work on RS-485.

    We used 1) Wiener filter for noise reduction from the fingerprint image received from optical sensor, 2) Local histogram equalization for uniform distribution of gray values, 3) Fourier transform of the image for contrast enhancement, 4) Anisotropic filtering for image enhancement, 5) Morphological operations for binarization and thinning of image. These steps were followed by minutae extraction and false minutae removal which would help in classification of image and matching.

  • Tribal Healthcare Information System

    Tribal Healthcare Information System

    Involvement as: Co-Principal Investigator

    Synopsis: Bhasha and Tribal Academy have developed a database about healthcare records of 45,000 adivasis living in Tejgarh area of Gujarat state. The database also contains contextual data related to various parameters like education, economy, population of village etc. Basic health is related to these parameters or may be more than these. For example, malnutrition should not be seen as a health issue in isolation. Rather it has a socio-economic linkage with the living standard of the family or the employability of the earning parsons of the family. There is a need to build database of people living in tribal areas of India and generate comparative analytical reports to help in planning of allocation of fund and other resources for tribal health care of India.

    Objectives of this project are: 1) To develop healthcare database of people living in tribal areas of Gujarat, 2) Develop a tool having capabilities to perform comparative analysis on multiple dimensions, 3) Develop user friendly GUI to provide support for retrieval based on various GIS parameters.

  • Value Addition in the Grassroot Technologies

    Value Addition in the Grassroot Technologies

    Involvement as: Co-Principal Investigator with Prof. Rahul Dubey

    Synopsis: This is a project for developing prototypes of six ideas that have been shared with us by some ignited young minds. Our role is to explore on the proof-of-concept of these ideas, their viability and finally deliver the working model of these ideas to the sponsors. The preamble of these ideas are:

    Idea # 1
    Charging Pen

    self charging pen-with charging capacitor-proto1-ver1

    Idea: We generally experience that energy is wasted while writing due to mechanical limitations of the simple pen. The energy wasted during writing can be used to produce small amounts of energy and charge embedded devices. We propose to develop a prototype pen capable of harvesting the energy exhausted as pressures while writing. The device will be able to store energy as electricity which can be utilized as per desirable use like charging a cellular phone etc. We propose to install piezoelectric sensors at points in the pen receiving repeated pressure such as the casing behind the refill and the holding positions. The piezoelectric material can be connected to a capacitive device for storing the charge. This charge can be extracted later for purposes stated above. The output can be taken via any desired port that can be installed onto the device.

    Idea # 2
    Text to Speech conversion System

    Text2Speech-step1-reading text-ver1

    Idea: The application targets a varied field of users. People from all walks of life can find use of such a device. While driving it is a major diversion when you need to read the number/name of the person calling you on your cell phone. A blind person is unable to read important things like signposts or news papers. The aim of this project is to create a multi purpose text to speech conversion system which can be used by everybody to make their daily lives easier. This device intends to help people multitask more efficiently by reading to them when they are unable to concentrate on the written matter. Existing technologies are majorly proprietary and expensive for the common user. We intend to develop the product under a constricted budget using open source libraries and minimal hardware for the purpose.

    Idea # 3
    Object Locator


    Idea: The primary purpose of the object locator is to help find lost objects inside a household. The object locator consists of a transmitter (which is with the user) and a receiver (which is attached to the object).Each receiver contains a buzzer and is associated with a particular address. The transmitter contains a switch and a mechanism to set address of a receiver attached to the lost object. When the switch is pressed the transmitter sends out an electrical signal containing the address of the receiver. The receiver receives the signal and matches the address with its own address. If the address of the receiver and the one which is set in the transmitter by the user is the same then the buzzer in the receiver starts buzzing. Using the buzzing of the receiver the user can find the missing object. The salient feature of the object locator is that only one transmitter is required to find multiple objects attached to multiple receivers by changing the address which is transmitted by the transmitter. The receiver can be attached to variety of objects like files, keys, remotes, etc. which easily get lost. The current implementation of the object locators supports receivers for 256 objects.

    Idea # 4
    Blind Person Navigation System

    Idea: A blind person faces many difficulties in carrying out day to day activities independently. One such difficulty is navigation through an unknown environment. The aim of the project is to develop a low cost and a robust navigation system for the visually impaired, which will help them to navigate independently in buildings like government offices, educational institutions etc. There are already many outdoor navigation systems available in the market, which work on GPS and GIS. However, technologies like GPS and GIS cannot be used for navigation inside a building. But our system will of help the visually impaired particularly for navigation inside a building.

    Idea # 5
    Smart Spelling Correcting Pen

    Self correcting pen-proto10-ver1

    Idea: Lot of times while writing we make spelling mistakes and there is no mechanism to know whether the spelling is right or wrong. If a system exists which informs us of spelling mistakes while writing, it could be of a great help. The objective is to make a pen that indicates that there is a spelling mistake in writing. The pen monitors the hand movement of a person and recognizes the letters written by the user. On the basis of this information the pen recognizes the words written and matches them to its on board dictionary and gives an indication if the spelling of a word is wrong. The pen uses optical sensors like the ones used in the optical mouse used with a personal computer. This sensor is aligned with the writing point of the pen thus monitoring the letters written. The pen has an onboard dictionary that it refers to for the correct spelling of a word, on a mismatch the pen gives a visual or audio indication that a wrongly spelt word has been written.

    Idea # 6
    Universal Refrigerator Grid System

    Refrigerator Grid-proto1-ver1

    Idea: The Universal Refrigerator Grid System is an electronic device which can be attached with any refrigerator. Its basic functionality is to work as a reminder alarm system. It is often experienced that housewives, or any person for that matter, who places a food item in the refrigerator for a certain period of time, forgets to take it out of the refrigerator after the required amount of time. This is often a source of inconvenience especially when the food item is an ice-cream or a water bottle kept in the freezer to chill. The Universal Refrigerator Grid System provides a solution for this problem. The system enables the user to set a timer alarm for the food item placed inside. The user may place the food item inside the refrigerator and set the timer to the required time. As soon as the time is set, the timer begins and at the end of the set time, the system gives off an audio alarm, reminding the user to take out the food item placed inside previously. Along with the audio alarm, the system also possesses a feature of displaying the name of the food item to be removed and the area of the fridge where it was kept. This functionality makes the system easily usable by any person other than the one who used it to set the alarm. Apart from the alarm and grid setting functionalities, the Universal Refrigerator Grid System also provides a functionality of display of the refrigerator grids. The refrigerator is virtually divided into grids by the system and the user is required to enter the grid in which he/she places the food item. After this information is fed in the system by the user, an overall view of the refrigerator grid can be viewed by the user which displays the number and positions of the grids occupied and unoccupied in the refrigerator.
