Re: Histogram Eqalization????

if p is the integer pixel value(0-255) and cumulative density function is
the density of cumulative histogram(0-1)

then p = round(cumulative density * 255)

where cumullative density is computed by this equation

cumulative density = cumulative histogram / image size
