hello guys, im working on a tree mapper, and during the night, i realised how to identify certain patterns of colours that a tree top would have. so now i have a bunch of points that represent where trees are located. the next thing BIG THING i need to do is to combine near points into one. BUT for the moment, im stuck at the
- ArrayList pts = new ArrayList();
- PVector point = new PVector(x, y);
- pts.add(point);
- for (int n : pts.size)
- {
- total += n;
- }
- println(total);
part, for some reason, the points arnt grouping up ..? or that i cant access the PVector array? im not really sure what is going on there.
below is the complete code:
- ArrayList[][] pts;
- PImage img;
- int count;
- int n;
- int num;
- void setup() {
- size(542, 166);
- background(255);
- img = loadImage("test small 1.jpg");
- image(img, 0, 0);
- }
- void draw() {
- img.loadPixels();
- for (int y = 7; y < height-7; y++) {
- for (int x = 7; x < width-7; x++) {
- // int loc1 = x - 5 + (y-5)*width;
- // int loc2 = x + (y-6)*width;
- // int loc3 = x + 5 + (y-5)*width;
- // int loc4 = x - 3 + (y-3)*width;
- // int loc5 = x + (y-3)*width;
- // int loc6 = x + 3 + (y-3)*width;
- int loc7 = x - 6 + y*width;
- int loc8 = x - 3 + y*width;
- int loc9 = x + y*width;
- int loc10 = x + 3 + y*width;
- int loc11 = x + 6 + y*width;
- // int loc12 = x - 3 + (y+3)*width;
- // int loc13 = x + (y+3)*width;
- // int loc14 = x + 3 + (y+3)*width;
- // int loc15 = x - 5 + (y+5)*width;
- // int loc16 = x + (y+6)*width;
- // int loc17 = x + 5 + (y+5)*width;
