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?
