To improve the accuracy of our machine learning classifier, we'll implement another feature where we measure how round a shape is. We do this by first computing the convex hull, then measuring its roundness by first calculating its length and area and comparing it with the area of a circle of the same length. Then, we add this feature to create a 4 dimensional feature vector and use the KNN classifier using the Euclidean distance.
