Paper-based processing still exists. It is going to stay for quite some time. Yes, not in just small business pockets but in a good 25-30% of business operation scenarios. When converted into monetary form, this aspect of business processing amounts to double digit millions annually in terms of revenue. The theme is majorly recurrent in BFSI and Finance & Accounts and Procurement sections of almost all Manufacturing, Telecom, Supply Chain, and Research & Analytics companies. Yet when it comes to business, you cannot compromise on speed, efficiency, and quality.

Top 38 pre-processing must haves for Intelligent Data Capture-1

As a matter of fact, Automation cannot take place without digitization. Simply put, Digitization is the stepping stone to your Digital Transformation journey.

It is interesting to note that, Document Processing or Optical Character Recognition (OCR) as it is popularly known, helps to digitize paper based enterprise assets. This actually leads to the materialization and fulfillment of complex business use cases.

However, the fact remains that OCR has inherent quality issues. A hindrance in the form of quality of the digitized asset renders even hi-tech technologies, such as Robotic Process Automation (RPA) and Intelligent Automation (IA), simply ineffective. Here, Intelligent Document Processing, more popularly known as Intelligent Data Capture software, is the way ahead. It enables you to read and ingest text from an image, thus making use cases such as Tab Banking, On-mobile Onboarding, and faster claim processing a matter of few minutes as against hours and days required in the bygone years.

Intelligent Data Capture is an integrated software, which has features of Optical Character Recognition (OCR), Optical Mark Recognition (OMR), as well as Intelligent Character Recognition (ICR).

What is Intelligent Data Capture software?

Intelligent Data Capture is the process of capturing data from all types of documents including “unstructured ones” such as email, text, PDF, scanned documents, etc., classifying it into categories, and extracting relevant information for further processing. The software solutions for Intelligent Data Capture use Artificial Intelligence algorithms to extract the data in a template free mode, process it, and then feed it into different applications, databases, and downstream systems.

However, at times the image itself is not clear, has carbon smudges, is skewed, and not properly oriented. At times, it could be a dot matrix print or have high noise and contrast. All this results in an inefficient data capture output as per the popular concept “Garbage in Garbage out” or “GIGO”.

It is interesting to note that the reliability and authenticity of the data captured depends on the clarity and effectiveness of the image captured. This calls for pre-processing of the image prior to data capture in order to enhance the image quality and improve the capturing process. It also requires certain post-processing to improve the quality of the data captured.

  14. Contrast: To increase or decrease contrast
  15. Brightness: To increase or decrease brightness
  16. Hue: Improves color depth
  17. RGB separation: Removes RGB color one by one
  18. Dotted line: Removes dotted lines for better OCRing
  19. Test registration: Aligns all images at a particular text
  20. In painting: Removes water marks incorporated as a separate layer
  21. Stamp removal: Removes stamp marks, which are in specific pre-defined color
  22. Edge smoothening: Makes lines perfect
  23. Character smoothening: Makes characters perfect

In summary

Intelligent Data Capture software along with RPA and IA provide a phenomenal success in many use cases, which were rendered simply impossible till a few years ago. The very fact that information from unstructured data sources such as a PDF, a printout, or even an image can be read and captured to update databases and downstream systems was highly unbelievable. Today, Intelligent Data Capture is a strong business enabler. It makes 3-minute on-boarding a digital reality, not only saving revenue in order of millions but also allowing you to do more with the same number of resources. Having said this, Intelligent Data Capture is just a milestone in the RPA and IA journey while leaving scope for more high-tech advancement in the near future.
