I have an unlabeled dataset: 500 X-rays of seeds in husk. In each image there are different number of seeds, for instance, from $10$ to $50$.
A seed has some features. The main features are a seeds' square and a husks' square in pixels. I need to calculate the these features ratio.
I am looking for an objects recognize algorithm. My problem is: I don't know what is a task type.
The dataset is unlabeled and I can use unsupervised learning and identify a similarity in groups (clustering task). Or I should to label data and use supervised learning and identify a real values (regression task)?
Question What is a task type?
