- Highlighting the silhouette of the object (maximum contrast between the background and the form) for dimension control
- Inspect absence / presence of holes
- Ideal for transparent and translucent materials (glass, fabric, printed circuit...)
- Liquid level control of bottle
- And many other machine vision applications.
