Fingertip in the Eye: An Attention-Based Method for Real-Time Hand Tracking and Fingertip Detection in Egocentric Videos
Communications in Computer and Information Science(2016)
摘要
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.
