Image Quality check parameters

There are several parameters that determine whether the image being processed passes the quality check or not.

Parameter	Default	Discription
imageQA.dpiThreshold	150	Set the threshold for an actual document DPI below which the check fails
imageQA.angleThreshold	5	Set the threshold for an actual document perspective angle above which the check fails
imageQA.focusCheck	true	Enable the focus check for the image quality validation
imageQA.glaresCheck	true	Enable the glares presence check for the image quality validation
imageQA.colornessCheck	true	Enable the colorness check for the image quality validation
imageQA.moireCheck	true	Enable the moire patterns check for the image quality validation
imageQA.Handwritten	2	For SDK 6.1 and above. Check for text to be NOT handwritten, because it is impossible to guarantee correct handwritten text recognition. If returns 1 - text NOT handwritten, if returns 0 - text IS handwritten and check counts as failed. If returs 2 - check is not defind.

You can specify custom quality checks that the image should pass to be considered a valid input during the scanning process using this as example:

DocReader.shared.processParams.imageQA.expectedPass = [.imageResolution, .imageGlares]

In this example, image will pass if only passes Image Resolution and Glares presents checks, ignoring all other checks results.
