Abstract: A new method for recognition and tracking of image object is advanced.The recognition and tracking of image object is carried out by drawing the human visual property,and by means of the image object indentifier, which is used to recognize and represent object. In particular, when the abnormal situation occurs badly i.e. when suddenly sun glaring or missing of the images object occurs in a short period of Time, the object can be recognized and tracked. The model of the image object identifier is presented using image algebra. Based on the model, the intelligent recognition and tracking of the image object in the led visual digital tracking system is discussed. Two visual tracking practical examples are given; one tracks plane and another tracks one of human legs, and show that the method in the paper is effective and applicable.
