At KlearStack we strongly believe that we are at the cusp of an emerging automation age driven by machine learning, artificial intelligence among other new technologies. Once considered to be too difficult to be automate tasks requiring cognitive capabilities successfully, OCR Technology- Optical Character Recognition coupled with AI has brought us to juncture where data can be captured from handwritten, printed, or typed text into machine-encoded texts and converted into interpretable data. More advanced versions of OCR are further capable of translating and interpreting text on physical documents.

Given the advancements in process automation in today’s businesses to improve productivity and efficiency, OCR has evolved to enable businesses to transform unstructured data to derive valuable insights and ultimately automate processes in a highly efficient and accurate manner.

What is an OCR application?

An OCR application or software uses OCR technology that is designed to work electronically to recognize characters from images whether scanned, photographed or native digitally generated. Most of these OCR softwares are designed to work with smartphone cameras or portable scanning devices. Earlier versions of OCR software required training with multiple images of characters to be able to recognize characters, especially from handwritten documents. Advanced versions have preloaded databases of fonts or handwriting or even use Artificial Intelligence to recognize handwriting.

OCR applications turns scanned images into text-based machine-readable files. With the help of OCR, paper-based documents can be converted into editable digital documents. With OCR, you can scan paper documents, easily archive them as digital PDFs, and easily save them.

OCR applications help reduce the amount of physical space required to store documents and make it easy to process bulk amounts of data. It is easier to process the digitized data in comparison to manual handling of data as it reduces the risk of lost and misfiled documents. OCR technology has dramatically reduced the cost of manual data handling.

A good OCR application does not only allow simple and seamless conversion but also provides cloud storage capabilities.

Application of OCR solution

  • PDF converter
  • Image preprocessor
  • Text Editor
  • ID scanner
  • Bulk document scanning


How to create an OCR application for Android?

  • If you are developing an OCR application, there are certain key features that you need to incorporate into your project.
  • Document Conversion: This is an important feature OCR application should have where users should be able to save scanned files in multiple formats. For example, text from scanned documents can be saved as a text document that can be edited or as a PDF. Conversion to other formats is an important requisite for an OCR application.
  • Multiple input formats: Users should be able to use different file formats as input, not just images, but other PDF or text documents also should be supported as input.
  • Libraries and API: API provides an easy way to integrate face detection, text detection, or barcode detection on android devices. We can just import the open-source libraries Library with Android Studio and implement the OCR for retrieving text from the camera preview.
