Example of segmentation of a knee joint from magnetic resonance imaging scans, manually performed by a human operator, automatically determined by a state-of-the-art deep learning method or with a novel method employing neural networks and a deformable model described in [10]. a Definition of the region of interests for femoral cartilage (green) and tibial cartilage (red); b manual segmentation created by an expert human operator; c automated segmentation obtained with a state-of-the-art deep learning method; d three-dimensional reconstruction of the automated segmentation; e, f filtered images enhancing the contours necessary for the novel approach; g, h segmented slice and three-dimensional reconstruction of the segmentation obtained with the novel method.
