SpotEllipsoidFeature

[stefanhahmann]

UserStory

From a biological perspective, the shape (approximated by an ellipsoid with 3 semi-axes and a resulting volume) of a cell during an individual timepoint may be a good descriptor for the cell type. Thus, it would be useful to have this information as a feature.

Acceptance criteria

1. Available as Feature within the Feature Computer
2. Computes the volume of the Spot
3. Computes all 3 semi-axes of the Spot/Ellipsoid

Tasks

• Implement Feature
• Implement FeatureComputer
• Write Unit test

Would you care to add the orientations?

Would you care to add the orientations?

Do you mean the division orientations? If so, this is a foreseen feature, once I will be working on features again:
