Fingertips Detection With Nearest-Neighbor Pose Particles From a Single RGB Image

Vision-based detection of fingertips is useful for freehand Human-Computer Interaction (HCI)—especially in virtual, augmented, and mixed reality—to have a seamless experience. The estimation of fingertips position in an RGB image involves overcoming various challenges like occlusion, appearance ambiguities, etc. The general approach relies on a two-stage pipeline involving hand location and detect...
