The behavioral recognition system with the motion templates was designed to recognize the 12 behavior types and the three behavior category types of turning, squatting, and moving arms behaviors.
The motion template is an effective method for tracking general movement, and it is especially useful for gesture recognition.
The process for the generation of CDM (change detection mask and motion template) is clearly shown in Figure 2. Let f k (x,y) be the k frame of the video sequence which is gray-valued.
The 44 motion detector templates were designed to identify working motions such as sitting down, moving arms, turning counterclockwise, turning clockwise, up-and-down, side-to-side.
Templates are designed so that they capture the structural and motion information that is most discriminative among activities.
Templates are displayed throughout wikiHow.
In other words, the motion estimation is already working well and the motion refinement with an inaccurate template is more likely to capture noise than true motion.
For slow-motion sequences, however, the 4D refinement template is not precise enough to increase the accuracy of motion estimation.
The general methods for breaking the symmetry in such systems, which is the essential condition for inducing motion, are template-based, leading to asymmetric objects.
