In the folder Code the function 'main.cpp' calculates the histogram equalization of an input image. 

In more detail, given in input the image called 'mare2.jpg'it would print:

-the original image (grayscale) [i.e. 'originale'] , 
-the histogram of the original image [i.e. 'istogramma imm originale'], 
-the equalized image [i.e.'immagine equalizzata da opencv']
-the histogram of the equalized image [i.e. 'istogramma equalizzato da opencv']. 

In the folder called results there are some image generated using this technique.
