Safety in railways is mostly achieved by automated operation using a specialized infrastructure. However, many tasks still rely on the decisions and actions of a human crew. Aiming at improving safety in such situations, we present an approach for recognizing railway signals and signs in video sequences taken by an in-vehicle camera. Our approach is based on a model automatically learned from examples,...
A novel fuzzy clustering based target extraction algorithm for FLIR imagery using spatio-temporal technique is presented. Firstly, in temporal domain, we establish the Gauss distribution model of frame difference background by incorporating the motion information of the target. And then, the infrared target region is determined based on change detection mask. Secondly, in spatio domain, the improved...
