1D Edge Detection

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.

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.

Locates a specified number of the strongest dark or bright pixel peak along a given path (without a scan map).

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

Locates a specified number of multiple pairs of opposite edges across a given path (without a scan map).

Very fast detection (or presence verification) of multiple pairs of opposite edges.

Locates multiple transitions between dark and bright pixels along a given path (without a scan map).

Very fast detection of multiple edge points - usually for object counting or displacement detection.

Locates multiple dark or bright pixel peaks along a given path (without a scan map).

Very fast detection of multiple thin structures like wires or scale marks - usually for counting or distance measurements.

Locates multiple pairs of edges across a given path (without a scan map).

Very fast detection of multiple pairs of opposite edges - usually for counting or width measurements.

Locates the strongest transition between dark and bright pixels along a given path (without a scan map).

Very fast detection of an object (e.g. horizontal displacement of a bottle) and simple measurements (e.g. liquid level in a bottle).

Locates the strongest dark or bright pixel peak along a given path (without a scan map).

Very fast detection of a thin structure like a wire or a scale mark.

Locates the strongest pair of edges across a given path (without a scan map).

Very fast detection or measurement of an object defined by a pair of opposite edges.
