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