Given a set of points, a convex hull is the smallest convex polygon containing all the points. In this paper, we describe a high-speed method for calculating the convex hull of 2D images based on Andrew's monotone chain algorithm. In our method, (1) all the points on a line in a given image are acquired in parallel, (2) only the points that can compose the convex hull are selected, and (3) the convex hull is concurrently built from the selected points during the previous steps. These three steps are successively executed until processing all lines in the image. We evaluate the performance of its FPGA and GPU implementation, and describe a detection method of surface-mounted devices as its application. |
