Human Detection and Tracking under Complex Activities

Multiple-target tracking is a challenging question when dealing with complex activities. Situations like partial occlusions in grouping events or sudden target orientation changes introduce complexity in the detection which is difficult to solve. In particular, when dealing with human beings, often the head is the only visible part. Techniques based in upper body achieve good results in general, but fail to provide a good tracking accuracy in the kind of situations mentioned before. We present a new methodology for provide a full tracking system under complex activities. A combination of three different techniques is used to overcome the problems mentioned before. Experimental results in sport sequences show both the speed and performance of this
