Histogram equalization - g00se - Oct 3, 2011 12:52 PM

I want to ask for histogram equalization. First i count histogram:

Code:

for (i=0; i<width; i++) {

        for (j=0; j<height; j++) {

            pixelValue = pixels[(j*width + i)];

            tablica[pixelValue] += 1;

        }

    }

Second thing is distribution:

Code:

for (int i=0; i<[histogram count]; i++) {

        sum += [[histogram objectAtIndex:i] intValue];

        [dystrybuanta addObject:[NSNumber numberWithInteger:sum]];

    }

But now i should count Look Up Table and apply this LUT at picture. Can anyone help me with this?
