Then, gray moments, a method making edge location to subpixel values, is used to improve the precision of the point clouds.
然后研究亚像素定位技术,应用形心法和灰度矩边缘定位法处理条纹,以求进一步提高条纹图像二维坐标的精度。

Gray clouds billow through the streets of the financial district and shroud the 16 acres where the towers had stood just moments before.
灰色的烟尘浪涌的通过了金融区街道并且覆盖了16英亩双子塔曾经站立的位置。
The use of moments for image analysis is straightforward if we consider a binary or gray level image segment as a two-dimensional density distribution function.
若把二值图或灰度图看作是二维密度分布函数，就可把矩技术应用于图像分析中。
I do not know if this is experimentally verifiable, but I have found that just remembering in detail those moments when I have felt high, vibrant and OK can lift me up out of the gray soup for a time.
我不知是否能用实验的方法来证实。但我发现当我热情高涨，富有活力，感觉良好时，详细的回忆起这些好的时候能使我在一段时期内摆脱这些痛苦的事情。
