Interaction through dynamic hand gestures is an interesting yet challenging area because in computer vision the hand is a non-rigid object that moves unpredictably. Additionally, the real-time backgrounds are unstable. RGB data of moving hand are sensitive to light variation and camera-view thus, continuous localisation of hand region in RGB images is strenuous. This paper proposes a unique solution that combines Scale-Invariant Feature Transform (SIFT) features with automatic feature extraction mechanism of Region-based Convolutional Neural Network (R-CNN), for robust tracking of moving hand in coloured video acquired through a camera with normal resolution. The efficiency of the proposed methodology is 96.84% in simple and 94.73% in complex background. The comparative analysis with contemporary techniques working on RGB images exhibits that the proposed solution gives high accuracy in a real-time environment. In the future, we can design an economical and user-friendly natural user interface using the proposed technique.
