a = imread('lena.tif');
figure, imshow(a);
[r,c] = size(a);
sum = 0;
fileID = fopen('exp.txt','w');
fileID1 = fopen('totalValue.txt', 'w');
for i=1:r
for j=1:c
value = a(i,j);
sum = sum + value;
fprintf(fileID,'%d\n', value);
fprintf(fileID1, '%d\n' , sum);
disp(a(i,j));
end
end
fclose(fileID);
fclose(fileID1);
Total some coming is 255. I am trying to get the per pixel value. Image size is 255x255.
Please help.

value = double( a(i,j) );
and please rename your variable sum as you are interfering with the use of the important function sum which is likely to cause you problems as you keep developing your program (including the problem that it confuses the people you are asking to read your code.)
