A new fully automatic femur segmentation method for CT images is proposed.
- class="label">•
This novel segmentation method defines both the femoral external surface and the medullary canal.
- class="label">•
The fast and automatic segmentation method is an important contribution for the development of surgical planning software efficient in terms of cost and time reduction.
