DetectSingleBarcode_Deprecated

Advanced

Module: Barcodes

Determines the position of a single barcode on the input image.

Applications

Detection of a barcode, but without actual recognition. Usually followed by a RecognizeBarcode filter.
Name Type Range Description
Input value inImage Image Input image
Input value inFormat BarcodeFormat* Format of the barcode
Input value inMinGradientLength Real 0.0 - Minimal gradient length of edge pixels used for detecting barcodes
Input value inBaseBarWidth Integer 1 - Estimated width of the thinnest bar
Input value inScanCount Integer 1 - Number of scan lines used in detecting barcode
Input value inScanWidth Integer 1 - Width of the single scan
Input value inMinStrength Real 0.0 - Minimal strength of an extracted edge
Input value inSmoothingStdDev Real 0.0 - Standard deviation of the gaussian smoothing applied to the profile extracted in each scan
Input value inPolarity Polarity Specifies whether code is darker or brighter than the background
