Abstract:

In the application of detecting ship on the surface of sea in the remote sensing field, the connected component labeling algorithm consumes lots of resources and time. A pixel-by-pixel scanning pipelined fast connected component labeling method is presented, and its hardware based on Field Programmable Gate Array（FPGA） is designed. The method performs a pixel-by-pixel scan on the image, and collects and edits the runs information of each row, and then obtains statistical information of each connected component by scanning the calculated runs, thereby extracting features. By optimizing the design, this method takes full advantage of the parallel processing of FPGA. The pixel-by-pixel scan is performed once, and no markup table is generated, so that the running time of the method is reduced, and the resource consumption is reduced. This method satisfies the requirement of real-time.
