According to the fact that background and object have different motion features
an object detection algorithm was proposed based on background motion compersation and hypothesis test. Motion vector was detected by a feature point corresponding algorithm and affine motion parameters were calculated through least square method. Difference image after compensation was detected by hypothesis test. After a series of morphological process
we obtained the intact moving object. Experimental results indicate that this algorithm can eliminate background motion effectivelly because of moving cameras and segment object under complex environment. The peak signal noise ratio has been improved 14.71 dB compared with two difference images.
