Adaptive Scaling - An approach to identify the degree of image scaling as a pre-processing step for OCR

Optical Character Resolution (OCR) Engines rely on good image resolution (obtained through manual scaling of images) to produce accurate results. Our R&D experts noticed no way to automatically arrive at each image’s scale factor. Hence, we embarked on a journey to create a matrix that provides a scale factor for a generic image set with varying resolutions.

In this whitepaper, you will learn about:

  • What is OCR (Optical Character Recognition)?
  • How does Adaptive Scaling optimize OCR performance?
  • How did our team determine the Ideal Scale Factors for different resolutions?
  • What did the performance tests demonstrate?
