Gray matter represents information processing centers in the brain, and white matter links the centers together.
灰质包含了大脑中的信息处理中心而白质将这些中心连接起来。
Gray matter represents information processing centers in the brain, and white matter represents the networking of-or connections between-these processing centers.
脑灰质代表大脑里的信息处理中心，脑白质代表这些处理中心间的协同与联系。
The original gray level image was changed into the macroscopical drawing information by pre-processing, threshold selection, image bivalency, edge detection and contour extraction and segmentation.
对原始数字图像实施预处理、二值化、轮廓提取及细化等处理后，将图像信息转变成宏观图形信息。
Edge information is important in image processing. The research of edge detection is based on gray image commonly. However, more edge information can be got from color image than that from gray image.
边缘信息是图像处理中的一种重要信息，通常的边缘检测研究是基于灰度图像的，然而彩色图像比灰度图像包含有更加丰富的边缘信息。
Image restoration is an important research subject in image processing. Image gray or gradient magnitude is used in most of image restoration algorithm and spatial information is not adopted.
图像复原是图像处理中一个重要的研究课题。大部分图像复原算法，都只是单纯地利用图像灰度或梯度信息，并没有考虑图像的空间结构信息。
