Feature request: Disable camera filters in the preview about passportscanner HOT 5 CLOSED

I think thats easy to do by changing the line:

camera --> exposure  --> highlightShadow  --> saturation --> contrast --> adaptiveThreshold --> renderView

into

camera --> exposure  --> highlightShadow  --> saturation --> contrast --> adaptiveThreshold
camera --> renderView

from passportscanner.

so you will live the filters in tact but don't send it to the renderview.
instead you will set the camera directly to the renderview
You will be missing some feedback about the quality of the lightning.
maybe you should change the adaptiveThreshold to a fixed threshold

Thanks, for your reply. Using your code the resulting image is not sent to the OCR engine. I've changed it in:
camera --> exposure --> highlightShadow --> saturation --> contrast --> adaptiveThreshold
camera --> crop --> renderView
and now it works but OCR is returning very bad results.

I've implemented a similar filter chain using the preprocessedImage method obtaining very good results.
I would like to switch the post processing mode with a boolean property in order to meet the initial requisite: have the camera preview free from filters.

If you like I can push the code for the community pleasure.
