Glimpses Into Census of IndiaGlimpses Into Census of India• India – Country with one of the Largest population in the World with approximately 1.27 Billion People Living in the Country

• Census Phases:-

House-listing Population Enumeration

• Census Organization has always experimented with new Innovations in the field of Information Technology

Impact of MIS on Census of India Impact of MIS on Census of India • Technology is necessity in Census because of the Large Volume of Data which requires Data Capturing and Processing

• Use of MIS in the Population has considerably reduced the time span of Census from 5-8 years to 3-4 years

• MIS has enabled us to make the Census Compact , Efficient Reliable and one of the best Archival Systems

• Use of Technologies like OCR/OMR and ICR has made the processes much more faster for the Enumerators

• Availability of System Integrators to help and Guide in the implementation of ICR Technology

• CAC :- Computer Assisted Coding used for Recognition of Handwriting

Role of System Integrator in CensusRole of System Integrator in Census• Responsible for Maintaining Data Security, Safety and Confidentiality

• Supply, Installation and Maintenance of SCANNERS,Form Processing Software

• Management of LAN and load balancing

• Impart operational training to the staff at each location

• Providing one Software Personnel at each site

• Providing scanner operators and carry out Scanning operations

•Creation of custom database files for recognizing Enumerators writing pattern

eFlow Process Customization

Results of Software CustomizationResults of Software Customization• First time 100% data captured, processed and released within five year of Census

• Auto Recognition Rate of upto 90% & false positive < 2%

• Manual Coding Replaced by Computer Assisted Coding

• Assimilation of IT skills internally in the organization due to frequent use and guidance by System Integrator

Steps Involved in the eFlow ProcessSteps Involved in the eFlow Process• ICR Used for Handwriting Recognition from a Written Sentence or a Printed Sentence into the Computer System to make the use of it and produce the same in the Soft Copy Format for future use

Here’s How ICR Works :-

• Scanning:- Paper based forms are scanned to create bitmap image file of the scans

• File Portal::- It is an Image File Registration module in eflow as an input to next activity

• Form Identification:- Automatically identifies the Images of various schedules based on the Empty Form Image (EFI) template created during the designing stage

• Manual Identification: Unidentified forms due to bad images are matched by the operator manually on computer with the help of EFIs .

• Processing: This module is heart and brain of the ICR technology. It automatically recognize the data (numerals/alpha) from the images with the help of various engines (CGK, AEG,KADMOS,TISICR etc)

• Tile: This module displays the images of similar digit at one place to identify any wrongly recognized character by system for correction and thus, enhances the accuracy and quality of data.

ICR Working (Continued)

• Completion:- Unrecognized or wrongly marked recognized characters in the Tiling will be presented for correction using images displayed simultaneously.

• Exception:- If any character image is not understood by operator at completion station (module), that will be corrected in Exception station by an officer competent to make decision.

• Export:- System exports the data generated in above steps to server for further processing like editing/aggregation/tabulation etc.

ICR Working (Continued)

Problems Faced from this Info.SystemProblems Faced from this Info.System• Difficulty in Handling Bad Images during the Scanning Process

• Bad Images due to Poor Paper Quality during printing

• Language Recognition Issues for the Software

• Failure of 1 Image Scanning Restarts the Whole Batch Process

• Not able to use color drop-out at scanning stage

• No Concurrency Check at Each stage of eFlow Process
