A method for separation of occluded persons in thermal infrared images is proposed. Firstly, an infrared image is preprocessed by a suitable segmentation method, so that the binary image, which indicates the regions of occluded persons, is available. Then, via mediod-shifts of spacial coordinates, the proposed method classifies the pixels of each region into medoid regions without prior knowledge and therefore adapts well to complex occlusion patterns in applications of infrared human detection.
