1D Edge Detection

Select a function from the list below.

Icon Name Description / Applications Modules
CreateScanMap

Precomputes a data object that is required for fast 1D edge detection.


Used together with 1D Edge Detection filters (excluding "_Direct"), but can be moved before the loop if only the scan parameters do not change.

MetrologyBasic
ScanExactlyNEdges

Locates a specified number of the strongest transitions between dark and bright pixels along a given path.


Very fast object detection (or presence verification) when the expected number of edges is clearly defined.

MetrologyBasic
ScanExactlyNEdges_Direct

Locates a specified number of the strongest transitions between dark and bright pixels along a given path (without a scan map).


Very fast object detection (or presence verification) when the expected number of edges is clearly defined.

MetrologyBasic
ScanExactlyNRidges

Locates a specified number of the strongest dark or bright pixel peak along a given path.


Very fast detection (or presence verification) of thin structures like wires or scale marks.
