Transfer learning network, and subsequent boundary distance regression and pixel classification networks for fully automatic kidney segmentation in US images. The boundary detection network (Bnet) is trained using a distance loss function and the end-to-end subsequent segmentation network is trained by combining the distance loss function and a softmax loss function.
