What would be the inverse of the following code?:
// Pixel at row r and col c (r >=0, c >= 0) unsigned char red, green, blue; unsigned char coded_red, coded_green, coded_blue;
unsigned short us = (red << 8) + (blue); us = (us << 5 ) | (us >> 11); unsigned int threebytes = (us << 8) + green;
threebytes ^= (101231 * c * c + 41231 * r * r);
coded_red = (threebytes >> 16) & 255;
coded_green = (threebytes >> 8) & 255;
coded_blue = threebytes & 255;
