This paper presents a formal theory for reasoning about motion of spatial entities, in a qualitative framework. Taking over a theory intended forspatial entities, we enrich ittoac...
We present here a theory of motion from a topological point of view, in a symbolic perspective. Taking space-time histories of objects as primitive entities, we introduce temporal...
This paper presents a new spatio-temporal motion estimation algorithm for video coding. The algorithm is based on optimization theory and consists of the strategies including 3D s...
Abstract. We present a qualitative shape description which has previously been proven to be useful for object categorisation. The description is based on a set of shape primitives ...
Multi-agent interactions often result in mutual occlusion sequences which constitute a visual signature for the event. We define six qualitative occlusion primitives based on the ...
