Spatial relationship of image semantics objects

In this paper, a spatial co-occurrence matrix (SCM) is proposed for representing the spatial relationship of semantic objects in images. The proposed SCM is established on both vertical and horizontal directions of interesting objects from the prototype spatial arrangement in images. The spatial relationships among objects can be retained directly in the prototype spatial arrangements, and then implicitly embedded in the proposed SCM. Furthermore, the calculation of spatial similarity among images can be implemented by calculating the distance between the SCMs.
