Abstract: In the modern war, recognizing and tracking the target rapidly and effectively is of vital importance for acquiring war initiative. For the sake, it is necessary to segment the target from the image accurately. In image segmentation, threshold selection is very important. The Otsu’s method is an effective algorithm for image segmentation, and has been widely employed in various real-time applications. In this paper, an implementation on FPGA of Altera's Cyclone II series for the BCVC (Between Class Variance Computation) of Otsu’s method is presented to meet these high speed requirements. The experimental results indicate that the system can obtain a good performance of image segmentation.
Keywords: Image segmentation; Maximum between class variance; FPGA
