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...
In this paper, we present a technique of detection and tracking of one or possibly more moving objects by implementing a "vector bank" into an H.264 based system-on-a-chip design architecture as a vision sensor in aviation systems, such as unmanned aerial vehicles (UAV). Most of the existing target-tracking algorithms are based on software solutions. The introduction of H.264 encoding chips...
Motion estimation (ME) is one of the bottlenecks in terms of the computational cost in a video encoder system. In this paper, we present a cost-effective method to calculate the "Vector Edge" of the current frame. We store all the vectors' information within a frame and put them in the Laplacian of Gaussian edge detection operator. It is similar to the image edge detection but we need to...
There exist a number of complex encoding techniques which make H.264 video coding much more efficient, such as the adoption of variable block sizes, multiple reference frames, and the consideration of rate-distortion optimization (RDO). However, these techniques come with a price, i.e. considerable increase of complexity due to the introduction of motion estimation (ME) and mode decision in the design...
