Resolved: Threshold for coins
How can we know that the values 150 and 110 are suitable?
Thank you for reaching out!
In the two previous lectures, Giles prints out the radii and the brightness values of each of the coins. You can see that the radii range between 89 and 120 while the brightness ranges between 75 and 190. Through trial and error, the values 110 and 150 for the radius and the brightness, respectively, had turned out to give the most accurate output. However, you are very welcome to test if the classification works with other values in these two ranges.
