AdaptiveNet: Toward an Efficient Face Alignment Algorithm

Xiehe Huang, Weihong Deng

Abstract: Face alignment, a challenging task in computer vision, has witnessed its tremendous improvement on the 300W benchmark. However, state-of-the-art algorithms are suffering from computational expense and therefore cannot apply in real-time. In this paper, we propose a time-efficient face alignment algorithm while maintain a sufficient algorithmic accuracy. Specifically, we adopt MobileNet-V2 as our backbone architecture to deal with easy samples, accompanied by a ResNet branch to handle hard examples. This combination leads to a low-latency and yet agreeable-performance design as our extensive experiment shows.
