Hi,
I am trying to implement a research paper using MATLAB. i have to to apply this three formula, respectively.
![son.png](https://www.mathworks.com/matlabcentral/answers/uploaded_files/245729/son.png)
for i=1:256
PDa(i) = hCL(i) / (width*height); % width*height = total number of pixels
end
CDa = zeros(1,256); %create CDa in formula
CDa(1) = PDa(1) ;
for i=2:256
CDa(i) = PDa(i) + CDa(i-1);
end
value_after_enhancement = zeros(1,256);
for i=1:256
value_after_enhancement(i) = 255 * CDa(i);
end
But maximum value of CDa is 0.109. So, i see a dark image (maximum pixel value is 3) as a result. I couldn't understand where the problem is in my code. Can you help me, please?
