linear stretching meaning in English

线性伸长

There are several effective methods which are used to improve image contrast , such as piecewise linear stretch , histogram equalization and histogram normalization and so on
采用图像对比度增强的方法改善影像灰度反差。主要的对比度增强方法有分段线性增强、直方图均衡化和直方图正态化等。
In course of image enhancement processing , this paper , by the means of radiation enhancement , spatial enhancement , image operation , color enhancement and rs data merge , thinks that the combined image by textural information image and original image can reflect both detail information and textural information while carrying out non - directional edge of the linear stretch image
在图像增强处理中,运用辐射增强、空间增强、图像运算、色彩增强、多源遥感数据融合等多种方法,经过多次试验对比,发现对线性拉伸后的图像进行非定向边缘增强,得到的纹理信息图像再与原始图像作叠加运算,得到的合成图像既突出了图像的细节信息又突出了纹理信息。
