This paper presented spatial relation descriptor based on metric matrix's eigenvalue which was invariant under translation,scaling and rotation.It was revealed by experiments that this spatial relation descriptor could describe one image similarly just as human beings'psychology,and it was robotic under translation,scaling,rotation and small noise,and also it had excellent similarity discriminating ability.Moreover,compared with classical spatial relation descriptors such as geometric method and map matching method,this descriptor could describe image better with lower computation.So this spatial relation descriptor will performance well in image recognition,image retrieval and image registration.
