Hardware implementation of the PBAS foreground detection method in FPGA

In this paper a hardware implementation of the state-of-the-art PBAS (Pixel-Based Adaptive Segmenter) foreground object detection algorithm in FPGA is presented. This background modelling and subtraction technique is using novel ideas which improve the detection results. In this work a research is presented that determines which parts of the original algorithm need to be adjusted and modified to allow hardware implementation. A comparison is presented how this modifications influence the results accuracy compared to the original software implementation and other algorithms. An example working system based on the proposed module using the evaluation board with Virtex 7 device is also presented. This is the first reported FPGA implementation of this algorithm.
