Function Documentation

CQualityAssessment_Create()

CQualityAssessment CQualityAssessment_Create	(	const CIDRS	argIdrs,
		idrs_exception *	pargException
	)

Creates a new CQualtityAssessment object to estimate the OCR quality on the provided image.

Returns

The newly created CQualityAssessment object.

Parameters

pargException

Pointer to exception structure that will be filled if an exception occurs

CQualityAssessment_Destroy()

void CQualityAssessment_Destroy	(	CQualityAssessment	argCQualityAssessment,
		idrs_exception *	pargException
	)

Destroys a CQualityAssessment handle.

Parameters

argCQualityAssessment	CQualityAssessment handle to destroy
pargException	Pointer to exception structure that will be filled if an exception occurs

If the result is:

• Between 0 and 50: the conditions for OCR are bad
• Between 50 and 90 : the conditions for OCR are acceptable
• Between 90 and 100 : the conditions for OCR are excellent

Parameters

argCQualityAssessment	CQualityAssessment handle
argImage	the input image
pcPerspectiveCorners	zone corners
pargException	Pointer to exception structure that will be filled if an exception occurs

Returns

An estimation value between 0 and 100
