If the image is greyscale the process is more or less straightforward , a pixels intensity corresponed to a height 如果一张图像是灰度图，过程又是查不多直接了当的，那么一样像素的亮度就代表了一个相应的高度。
The original method just can be used in removing the noise from binary images . the gray images contain much information about writer habit 原算法只运用于对黑白二值图像去除噪声，而灰度图带有更多的反映书写人习惯的特征信息。
Real - time rendering of watercolor effects for virtual environments . in proc . ieee pacific - rim conference on multimedia , tokyo , japan , nov . 2004 , pp . 474 - 481 在对这些灰度图象进行简化时，我们采用高斯滤波来提取所需的视觉简化表达。
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。
Starting from this premise , we can easily conceive a height map as a greyscale image , where the intensity of each pixel corresponds to a height 在这个前提下，我们可以很容易的想到高度图就是一个灰度图，每个象素的强度值就为相应的高度值。
Evaluation method is formed , in which jamming effects and performances of suppression methods can be evaluated by gray image , snr and correlation coefficient 并形成了基于复图像的评估方法,即以灰度图、信噪比和相关系数来评估干扰效果及后续干扰方法的优劣。
Fingerprint image pre - processing has five parts : filtration in gray - scale image , binarization , filtration in binary image , thinning and filtration in thinning image 指纹图像的预处理又可以分为灰度图滤波去噪、二值化、二值化图像去噪、细化和细化后去噪五个部分。
For the sake of identifying some blurred images , a fuzzy template matching algorithm based on analysis of binary images " variability and its improved scheme is presented 为了实现对模糊汉字灰度图的识别，提出了基于二值图形变动分析的模糊模板匹配算法及其改进方案。
There are many methods of image segmentation , such as the segmentation based on prey image , the segmentation based on color image , the segmentation based on information theory , etc 虽然现有的图像分割方法很多，如基于灰度图的分割、基于彩色图的分割、基于信息论的分割等等。
The opposite route is also possible , i . e . form a terrain , and its height map , it is possible to create a greyscale image , where each pixel ' s intensity corresponds to a relative height 相反的路线一样是可行，例如，从一个地形，它的高度图，我们可以创建一个灰度图，让其每个象素的强度代表相应的高度值。
