Fingertip in the Eye: An Attention-based CNN Method for Real-time Hand Tracking and Fingertip Detection in Egocentric Videos



报告摘要

With the development of smart wearable cameras such as Microsoft HoloLens and Google Glass, the egocentric vision and its applications have drawn lots of attention of people from various fields. We are particularly interested in its vision-based interaction with human. The hand and fingertip-based gesture interaction could be the most appropriate approach because it acts like a virtual mouse to which people get used.

The hand and fingertip tracking is the crucial part in the egocentric vision interaction, and it remains a challenging problem due to various factors like dynamic environment and hand deformation. We propose a convolutional neural network (CNN) based method for the real-time and accurate hand tracking and fingertip detection in RGB sequences captured by an egocentric mobile camera. Firstly, we build a large scale dataset, Ego-Finger, containing plenty of scenarios and human labeled ground truth. Secondly, we propose a two stage CNN pipeline, i.e., the human vision inspired Attention-based Hand Tracker (AHT) and the hand physical constrained Multi-Points Fingertip Detector (MFD). Comparing with state-of-the-art methods, the proposed method achieves very promising results in the real-time fashion.
