abstract = "3D Instance Segmentation (3DIS) of Point Clouds (PCs) is valuable
for applications like autonomous vehicles, robotics, and Building
Information Modeling (BIM). Current work on this topic is guided
mainly by global metrics like mAP, which arguably do not support a
deep, informed analysis of technique tradeoffs and, more
importantly, directions for improvement. Qualitative analysis is
widely adopted to provide such guidance, but it is generally
implemented ad-hoc. This is true across many tasks in Deep
Learning, but PC 3DIS is especially challenging to visually
analyze due to the many variables involved: three spatial
dimensions, colors, semantic labels, and instance IDs. We propose
REIS, a visual analytics tool for Rendering and Exploring Instance
Segmentation results. It supports qualitative analysis in two
ways: first, through PC renderings targeted at efficient
investigation of 3DIS results; second, by providing a systematic
way to explore these results via the interactive Instance
Detection Matrix- a confusion matrix analog that summarizes error
and success cases, and allows the user to navigate through them.
To show the efficacy of REIS, we use it to evaluate a
state-of-the-art 3DIS approach on the S3DIS dataset. Our code is
available at https://github.com/pedrosidra/pcloud explorer.",
