A rotationally invariant template matching using normalized invariant moments is described. It is shown that if normalized invariant moments in circular windows are used, then template matching in rotated images becomes similar to template matching in translated images. A speedup technique based on the idea of two-stage template matching is also described. In this technique, the zeroth-order moment is used in the first stage to determine the likely match positions, and the second and third-order moments are used in the second stage to determine the best match position among the likely ones.
介绍了一种使用归一化不变矩的旋转不变模板匹配方法。结果表明,如果在圆形窗口中使用归一化不变矩,则旋转图像中的模板匹配就类似于平移图像中的模板匹配。还描述了一种基于两阶段模板匹配思想的加速技术。在该技术中,零阶矩用于第一阶段来确定可能的匹配位置,二阶矩和三阶矩用于第二阶段来确定可能的匹配位置中的最佳匹配位置。
