Abstract: The paper proposes a location method for an object obtained in an image sequence based on Adaboost.The Adaboost is employed to classify the pixel around the object into the object part and the scenery part according to the prior knowledge.The morphology is used to adapt the miss classification and noise for the object pixels.According to the object moments，the center of the object，that is the location result，is obtained.The algorithm solves the effect of complexity pixel value in the procedure image segmentation.The experiment results show that the proposed method is effective.
