Abstract :
In this paper, we present a design architecture of implementing a ¿Vector Bank¿ into video encoder system, namely, an H.264 encoder, in order to detect and analyze the moving objects within the specific area. Also, we believe that the transmitting bandwidth could be saved with the implementation of Vector Bank design. Motion Estimation is a common technology for today´s video codec. By abstracting the vector data from the Motion Estimation block using the motion detection method and with the application of Laplacian of Gaussian operator, we could obtain the object motion data generated by up to 16 reference frames. Thus, it could save the bandwidth, processing load, and memory resources dramatically.
