Bubble Sort Code

PImage img;

  size(400, 500);
 img = loadImage("http://c2.staticflickr.com/2/1618/24388577776_d20f68c13e_n.jpg");
  img.resize(width, height);

void draw() {

  //load on
  img.loadPixels();

  color[] pxls = img.pixels;

  //do something with the pixels (remix them)
  for (int y =0; y < img.height; y++) {

    int offset = y * img.width;

    for (int x = 0; x <img.width - 1; x++) {


      //indices for left and right pixel
      int left = offset + x;
      int right = offset +x +2;

      //bubble sort step

Final Project Progress

1. Image 1 2. Image 2 3. Blend 4. Add 5. Subtract 6. Darkest 7. Lightest 8. Difference 9. Exclusion 10. Multiply 11. Screen 12. Overlay 13. Hard Light 14. Soft Light 15. Dodge 16. Burn

Notes: 'Subtract' only picks up on extreme differences. 'Darkest', 'Lightest' and 'Difference' could be useful. 'Difference' continually flickers in draw mode.
