Scanning/processing on Android phone/tablet

Post by bookscanner » 16 Jul 2018, 16:40

I'm developing Android application for complete book processing workflow (useful in libraries etc).

Currently implemented camera image processing with various filters, every filter can be added/removed, enabled/disabled and configured with immediate result display.
For now available regular filters (brightness/gray/mono (several algorithms),rotation/crop etc).
More sophisticated (dekeystoning/dewarping/deskew/despeckle etc) are planned.

I don't want to discourage the bookscanner, but I had recently seen a software by Adobe for this. How does that compare to yours?

Adobe Scan? I don't know, it requires registration. As I understand, its more automatic, without full control / fine tuning of applied filters, and its not standalone, some operations (OCR etc) require connection to Adobe services/cloud
