| Abstract | (in Japanese) | (See Japanese page) |
| (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 αk and αl long 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. | |
