I = imread(image.png); %reading image,, change image name

imshow(I) %displaying image

figure;

imhist(I); %generating histogram of image

c)

%histogram-equalization

I = imread(image.png); %reading image,, change image name

imshow(I) %displaying image

figure;

imhist(I,64); %generating histogram of image

j = histeq(I); %histogram equalization function

figure;

imshow(j); %displaying

figure;

imhist(j,64);
