PDF417DetectionParams

Description

Specifies how PDF417 codes are being detected.

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

• float ContrastThreshold = 5.0f - Guaranteed gray level difference between dark and bright modules
• float ContrastHysteresis = 0.0f - A value dynamically subtracted from ContrastThreshold to improve local segmentation
• int DetectionScanCount = 3 - Number of scan lines used for detecting the code
• int ScanWidth = 1 - Width of the single scan
• float SmoothingStdDev = 0.6f - Parameter for gaussian smoothing used during scanning
• float MinEdgeMagnitude = 8.0f - Minimum acceptable edge strength
