Image enhancement using Tesseract and Ionic 2/3

[sunit.k...@ves.ac.in]

We are developing an app with OCR capability using Ionic and Tesseract. We are successfully able to capture the image using device's camera but we want to enhance the image using some advanced filters. We came across this link : 

https://github.com/tesseract-ocr/tesseract/wiki/ImproveQuality 

The link does not mention anything about ionic but we would want to achieve something similar to this link.

We would appreciate if someone could tell us any open source APIs/SDKs/tools to that can be used with Ionic. 

Thank you.
