DataMatrixDetectionParams

Specifies how data matrix codes are being detected.

Type fields and default values (if defined) are described below:

Name	Type	Default	Description
ContrastThreshold	Integer	10	Guaranteed gray level difference between dark and bright modules
ContrastHysteresis	Integer	0	A value dynamically subtracted from ContrastThreshold to improve local segmentation
ContrastPerturbations	Integer	0	Number of perturbations applied to ContrastThreshold for improving possibility of detection when lighting conditions are highly variable
DynamicSNRatio	Integer *		Signal-to-Noise Ratio that dynamically increases ContrastThreshold; use with low values of ContrastThreshold
NonBinarySegmentation	Bool		Assumes that there might be pixels significantly brighter or darker than the foreground or the background modules in near proximity of the quiet zone; use with DetectionMethod=FinderPattern
ForceIsotropy	Bool		Switches to image preprocessing methods that give more stable results for different code rotations
DetectionMethod	DataMatrixDetectionMethod	FinderEdges	Specifies which feature is used for code detection: the shape of the finder pattern or the blob of the quiet zone
PyramidStrategy	DataMatrixPyramidStrategy	Precise	Specifies the step of image downsampling used for finding codes at different scales
OutlineStrategy	DataMatrixOutlineStrategy	Precise	Specifies precision of outline detection
FinderTradeoff	DataMatrixFinderTradeoff *	Balanced	Decides whether to optimize parameters for weak edges (sensitive) or for jagged ones (robust).
