Evaluating ratio meat/fat 2
A similar analysis was done before, with images copied from the internet. This time the images are taken by myself with the tablet's camera. I bought the meat too myself at the local Kroger:
"PVT selection angus choice boneless beef ribeye steak", 0.56 lb, $5.59.
The amount of meat is captured by a red contour above. The screenshot is below.
As you can see in the right bottom, (the area of) the meat is about 42% of the whole image.
Now we need to capture the fat. It's tempting to try to do it directly but capturing light area with white background is never a good idea. It's much easier to get the whole thing and then do some math.
The total of the whole steak (meat and fat) is about 57% of the total image.
Hence, the amount of fat is (57-42)/57, or about 26%. Not lean!
