零阶矩 meaning in English

zeroth moment

Then 3 kinds of recognition algorithm , including zeroth order moments , gray histogram and color histogram , have been tested for this system
分别用几何零阶矩和图像的灰度、彩色直方图的方法进行识别。
Form the experiment results , we can see that zeroth order moments method is not appropriate for this reconstruction and recognition system because it discards all the detail information of an image color and texture . however , considering on all pixel color , color histogram is suitable for this recognition system
从仿真结果可以看出，由于零阶矩没有利用图像的全部颜色细节和纹理信息，识别效果不是很好，而彩色直方图比较的方法是针对于上述飞机模型库进行识别的合适的方法。
