| Abstract: | A method for detecting moving object from videos is provided when undergoes a dynamic scene.The method is based on the algorithm of the SURF and the global motion of the image is modeled as rotational parameters,the least square method can precisely compute the motion parameters which then leads to the implementation of motion compensation and the object detection.In this process we using ORSA algorithm to eliminate the outliers which is gen-erated in the process of feature points matching,after that the le... |
