Vision Sensor Manual

If in this area edges are found with different polarity (dark- bright: positive polarity, bright-dark: negative
polarity) it´s edges steps can neutralize each other. This can be used to eliminate residual edges, by
choosing a sigma value which is high enough.

Fig. 333: Edge detection with sigma value = 1. Residual edge is not eliminated.

Fig. 334: Edge detection with sigma value >> 1. Residual edge is eliminated.
