Calculating IoU and ConfusionMatrix for Object Detection

In this homework we will write Python code to calculate the Intersection-over-Union (IoU).

1. Implement IoU in Python

Implement two functions: calc_iou(). PyTest will be used to verify your code.

2. Complete the class ConfusionMatrix

Complete the member function process_batch() of class ConfusionMatrix in obj_det_metrics.py

Note: Please do not modify the code of iou_test.py and cf_mat_test.py
