Jaccard index between different types of segmentaiton result and ground truth.

[elboyran]

The segmentation result could be either pixel or grid Binary Mask (BM) or a (multipolygonal) Shape (S). The ground truth can be either a shape file or sometimes - pixel mask. In this issue consider comparison between different types segmentation result and ground truth: BM <-> S.

This can be achieved by conversion from BM to S and then comparing 2 Shape files or S to BM and comparing 2 BM.

It is currently unclear how to save a multipolygon to a shapefile (with Fiona)?

The last notebook (N 5) has a problem of getting a not-valid multi-polygon from a binary mask- how to solve it!??
