Fig. 3From: LandmarkNet: a 2D digital radiograph landmark estimator for registrationExample outputs produced by our network. a, b, c represent Spinous process, Tracheal bifurcation, Louis angle respectively. The images on the left are the inputs of our network. To show the points of interest, we manually marked them with different red geometric shapes and the landmark is located in the centroid of the geometry marked with blue dots. The middle images are the output heatmap of the network. On the right are the images processed by NMSBack to article page
