Abstract
Omnidirection camera is a special camera having 360 degrees view. Gripping the camera with fingers, and using the camera image with finger motion for human machine interface is proposed in [1]. In this paper, we track the motion of fingers in the image of the same setting in [1] by using a state space model, which represents state and image observation of the fingers. State estimation is conducted by CONDENSATION algorithm[3], which is one realization of particle filters[2] maintaining posterior distribution of the state by many samples (particles) according to the distribution, i.e. the distribution is approximated by degree of dense of the samples. Experiment of finger tracking has been conducted, and usability of the algorithm is demonstrated.
