The probability that Q lies in the interior of H at time t is obtained for two types of motion of the particle, rectilinear (i.e. straight-line) and Brownian. In the case of rectilinear motion, the first passage time through the boundary of H is considered. Results are obtained in terms of the generalized overlap function for embedded bodies.}, number={2}, journal={Image Analysis and Stereology}, author={Ehlers, Peter and Enns, Ernest and Fung, Tak}, year={2011}, month={May}, pages={113–117} }
