[Other] carnum DL : 0: 1. 分量法。 2.最大值法。选取彩色图像中的三分量中（RGB）的颜色的最大值作为灰度图的灰度值。即：f(i,j)=max(R(i,j)，G（i,j）,B(i,j))。 3.平均值法。将彩色图像中的三分量亮度求平均得到一个灰度图f(i,j)=(R(i,j)+G(i,j)+B(i,j))/3。 4.加权平均法。(The 1. component method. 2. maximum value method. The maximum value of the color of the three component (RGB) in the color image is selected as the gray value of the gray scale. That is: F (I, J) =max (R (I, J), G (I, J), B (I,)). 3. mean value method. A gray image f (I, J) = (R (I, J) +G (I, J) +B (I, J)) is obtained by averaging the brightness of the three components in a color image. 4. weighted mean method.)
