dosma.tissues.FemoralCartilage¶
- class dosma.tissues.FemoralCartilage(weights_dir=None, medial_to_lateral=None)[source]¶
Handles analysis and visualization for femoral cartilage.
This class extends functionality from Tissue.
For visualization, the femoral cartilage is unrolled onto a 2D plane using angular binning [1].
