Learning Active Contour Models for Medical Image …
edge of the ACMs firstly proposed by Kass et al. [13]. ACM models treat segmentation as an energy minimiza-tion problem where the energy of an active spline/contour is minimized by PDEs-based methods toward the objects’ boundaries. In classic ACMs, detecting objects’ boundaries is by image gradients. However, this has one main lim-

What Have We Learned From Deep Representations for …

In the discriminator network, the basic GAN [17, 12, 8] is trained to distinguish the real and fake high resolution images. To classify faces or non-
