This example uses Otsu’s method to combine two sources (two different images of the same object) to get an optimal threshold. The idea is to get a weighted average of two images as follows
\[\mathcal{I}
=
(1 - \alpha) \mathcal{I}_a + \alpha \mathcal{I}_b\]
whereby \(\alpha\) is chosen such that the separability, defined by Otsu is maximised.
