Firstly, considering the requirement for time crisis, a gray-level transformation method based on shifting operation is put forward.
首先，根据移动机器人的实时性要求提出了基于移位运算的灰度变换方法。
To obtain defect images through appropriate approach and conduct gray-level transformation, and the images are enhancement processed with median filtering, so as to get ready for further processing.
通过确当的途径获取缺陷图像，并对图像进行灰度变换，中值滤波对图像进行增强处理，为下一步图像的进一步的处理做前期的准备。
Thus, we propose that the blend of a full-color image can be viewed as superposition of two complementary gray - level transformation images.
这样，可将图像的合成看作两幅图像互补的灰度变换的叠加。
