Extract Oriented Labels

The Extract Oriented Labels extracts every label from the input label image, and resamples each image along its own main orientations (or eigenvectors).

It is also possible to specify precisely which axis of the coordinate system of the extracted label the main orientation (or first eigenvector) must be aligned with after the resampling is done.

A further optional automatic crop step can be performed after the resampling is done to guarantee that the bounding box of the extracted label is optimum (smallest possible).
