Hi, I give you an example that is the average histogram for 3 planes (R,G,B) of an image (I), You can change the histogram for multiple images as you need.

I=imread("filename");
r = I(:,:,1); g = I(:,:,2); b = I(:,:,3);  
[counts1,nb] = imhist(r);
[counts2,nb] = imhist(g);
[counts3,nb] = imhist(b);
Average_counts = round(mean([counts1(:), counts2(:), counts3(:)], 2));
