2. Project Motivation
Between Chris and Nicole we have 40+ years of curling experience
Most important aspect of a curling delivery is level shoulders
Improvement to the standard way of delivery verification

8. Code - Image Processing Algorithm Prototype
for(int i = 0; i < img.getWidth(); i++){
for(int j = 0; j < img.getHeight(); j++){
rgb = getPixelData(img, i, j);
int t = rgb[2] + rgb[1] + rgb[0];
if ((t/3 < 100 && rgb[2] > 100) || (t/3 < 150 && rgb[2] > 150 )){
Color w = new Color(255,255,0);
img.setRGB(i,j, w.getRGB()); }

9. Image Processing: Before and After

10. Challenges Features to Add or Remove
