| 摘 要： | 针对采用图像二维不变矩匹配时,计算量大、耗费时间长的缺点,提出了一种基于不变矩特征匹配的快速目标检测算法.该算法首先用滤波后的图像直方图不变矩进行匹配,匹配成功后,再用图像二维不变矩进行检验和确认.实验表明,该方法能有效抵抗图像对比度、亮度及旋转的影响,并且大大减少了运算时间.

| Abstract: | To improve the speed of matching with two dimension invariant moment of image, a fast target detecting algorithm based on invariant moment is put forward. First, the algorithm uses the invariant moment of image histogram filtered by mathematical morphology method to match, then two dimension invariant moment of image to test and verify. The experiment shows that the method can resist the effect of the brightness,contrast change and rotation of image, and reduce calculating time greatly. |
