Why the G color plane curve of four different groups of image plotted against another constant variables has different shape from its average value?

I have seven green colour images of different intensities at different spatial positions. i used four different positions to find out the difference in color plane results.the green color plane curve plotted against another constant variables of these images produce dissimilar curve shape(i.e. green color plane value differs when i change its position in x-axes). what could be the reason a same image has different green color plane value at different positions. the codes that i had used in this task is: a=0.85; for i=3:9 filename=strcat('D:\2nd year\EXP season 2\Dry\cat1\',num2str(i),'.bmp'); I=imread(filename); I1=I(:,:,2); I2=I(:,:,3); G_channel_cat1(i-2)=mean(mean(I1(293+(-5:5),250+(-5:5))))-mean(mean(I2(293+(-5:5),250+(-5:5))))*a; end

I'm not sure what you're saying. It's like you're asking "How can different images have different values in the green channel?" But that can't be it because the answer to that is obvious. So can you rephrase what you're asking and perhaps upload some images, diagrams, plots, screenshots, code, or anything else that might help illustrate your situation? Also explain exactly what are "the other constant variables".

Again, a picture would be helpful. Also outline the regions of interest so we can see what you're looking at.
