| 摘 要： | 在图像分析中，水平积分投影和垂直积分投影被用来描述目标的灰度分布结构，其缺点是很难用简单的关系将旋转前后的积分投影后的曲线与相同的目标对应起来。因此，提出基于圆周投影的圆周积分投影和圆周梯度积分投影两种图像灰度分布的统计方法。与水平积分投影和垂直积分投影方法进行了比较。实验结果表明，圆周积分投影和圆周梯度积分投影曲线具有良好的旋转和尺度不变性。

| Abstract: | In image analysis, horizontal integral projecting and vertical integral projecting algorithms are usually utilized to describe the gray distribution of targets. If targets rotate, it is difficult to find the relationship among the projecting curves of the same targets in different orientations. In order to overcome this default, two kinds of statistic methods called circular integral projecting and circular grads integral projecting are proposed based on circular projecting. Furthermore those methods are compared with horizontal integral projecting and vertical integral projecting. The experimental result shows that the curves corresponding to circular integral projecting and circular grads integral projecting own excellent steadiness when target rotates and flexes. |
