SoHysteresisThresholdingProcessing image filter. The SoHysteresisThresholdingProcessing engine computes a SoHysteresisThresholdingProcessing threshold.
The SoHysteresisThresholdingProcessing uses a SoHysteresisThresholdingProcessing loop to provide a more connected threshold result.
Two gray level values and and ( thresholds parameter) are specified. The output is given by:
- If , the point is in the and is preserved:
- If , the point is in the :
- If , the point is in the . The point is preserved if connected to a retained area ( ), or is rejected if not ( ).
The Figure shows the result of a lower bound threshold with value and . Figure is the result of an SoHysteresisThresholdingProcessing, where the points in the fuzzy area not connected with points in the retained area are rejected.
This command can be used after an edge detection, which generates, as well as edges, a lot of noise. True edges have a higher chance to be connected to a retained area than pixels corresponding to noise.
