Nettet1. nov. 2024 · 1. Introduction We introduce a new problem in 3D point cloud: few-shot instance segmentation (3DFSIS). Given a few annotated point clouds exemplified a target class, our goal is to segment all instances of this target class in a query point cloud. This problem has a wide range of practical applications where point-wise instance … Nettet24. aug. 2024 · IoU is an important accuracy measure to track when gathering human annotations.

The predictions are accumulated in a confusion matrix, weighted by `sample_weight` and the metric is then calculated from it. If `sample_weight` is `None`, weights default to 1. Use `sample_weight` of 0 to mask values.

NettetThe IoU value is calculated as an average over predicted instance IoUs, not annotated object IoUs.
