| Abstract(in English) | In this paper, we describe an approach for detecting patterns in various size and angle using FPGA. In our approach, the image is downscaled by α^k and α^l along the x and y axes(k,l=0,1,2,...,n), and the regions in the downscaled images are compared with several sequences of the templates which are generated from the given pattern using direct cross-correlation. This approach requires high computational cost, but by calculating the cross-correlations incrementally starting from the non-rotated pattern, it becomes possible to detect the rotated patterns in various size with one FPGA. |
