Mean Intersection over Union (mIoU) for 3D Semantic Segmentation

post image

The mean Intersection over Union (mIoU) is a metric which is often used for measuring the goodness of e.g. 2D- and 3D semantic segmentation and object detection systems, by comparing the predictions made by a system to the ground truth labels. In this post, we will show how the mIoU is calculated for a very simple 3D point cloud toy example...
