| Watershed |
This demonstration shows the segmentation of images by the watershed algorithm. The implementation is based on the immersion process analogy, using the gray levels as a topological relief.
The objects to be separated should be dark, i.e. low gray values.
We recommend smoothing the image in order to avoid over segmentation. |
Instruction to use the applet
- Choose an input image in the list.
