CNN architectures. Left: The vanilla network described in Sec. 2.1 for facial landmark regression. We show that representations extracted from the input to FC5 (marked in red) are highly specialized and reflect facial alignment. Right: Our Tweaked CNN (TCNN) design, diverting intermediate features to K different subsequent, fine-tuned processes in the same dimensions as the original layers.
Abstract: We present a novel convolutional neural network (CNN) design for facial landmark coordinate regression. We examine the intermediate features of a standard CNN trained for landmark detection and show that features extracted from later, more specialized layers capture rough landmark locations. This provides a natural means of applying differential treatment midway through the network, tweaking processing based on facial alignment. The resulting Tweaked CNN model (TCNN) harnesses the robustness of CNNs for landmark detection, in an appearance-sensitive manner without training multi-part or multi-scale models. Our results on the AFLW, AFW, and 300W benchmarks show improvements over existing work. We further provide results on the Janus benchmark, demonstrating the benefit of our better alignment in face verification.
