A Robust Fingertip Detection Algorithm for Mobile User Interfaces

A robust algorithm for finger-gesture-based mobile user interfaces (UIs) is presented. The proposed algorithm adopts edge detection for fingertip detection, which is robust to changes in lighting conditions for mobile UIs based on finger gestures. The proposed algorithm has low complexity, and can easily cope with real-time processing using rear-facing cameras in mobile phones. Experimental results demonstrate that the proposed algorithm has better correct-detection probability than the conventional algorithm in various environments.
