Abstract

Multi-dimensional spatial occlusion relation (MSO) is an observer-centred model which could express the relation between the images of two bodies x and y from a viewpoint v. We study the basic reasoning method of MSO, then extend MSO to spatial-temporal field by adding time feature to it, and the related definitions are given.
