- There is spatial correlation between the neighbored pixels, so there is the adjacent gray value. 大多数图象具有空间相关性,绝大部分相邻的象素点具有相近的灰度值。
- The noise pixels are removed using the improved median filtering，while signal pixels hold their gray value and are unprocessed. 同时，在去除噪声时只利用信号点参与中值滤波，并让噪声点逐步转化为信号点，减少了噪声在邻域的传播。

- In chapter IV , a new method of eyes location is provided. It detects the edg of human face image with wavelet transform in the first. Then it begins to statistic the gray value of the row and list. 本文第四章提出了一种基于简单背景的人眼定位算法，用小波变换对人脸图像进行边缘检测，对得到的结果进行行列统计，得到人脸的大致位置，再用模板匹配进行最后的精确定位。
- In so doing the original image is decomposed into lots of integral sub-blocks, and the position, size and gray value of each integral sub-block can be stored with an efficient way, so as to achieve the aim of compression. 该方法把原始图像分解为若干个整体子块，并采用有效的方式存储每个整体子块的位里、大小和灰度，从而达到压缩的目的。
- In the old rat, the gray value of AChE-P neurons of the globus pallidus is notably higher than that in the young rat, but the value of nearly 6.8% of the positive cells in 24-month-old rat is inferior to the average value in 3-month-old rat (117.8). 老龄苍白球AChE-P神经元的灰度值;明显高于幼龄组;但约有6.;8%25老龄阳性神经元的灰度值低于幼龄的平均灰度值(117
- It classifies matching pixels by dynamic threshold. If absolute difference of gray value is more than threshold, it counts the minimum absolute difference square of the gray level of the two images. 它先对匹配像素用动态阈值分类,若灰度绝对差大于阈值,再使用最小绝对差平方累加和作为相似性度量。
- This paper presents a new impulse noise filter based on pulse couple d neural networks according to the apparent difference of gray value between noi sed pixels and the pixels around them. 根据脉冲噪声与其邻域中图像灰度之间的明显差异性,本文提出了一种新的神经网络脉冲噪声滤波器设计方案。
