- Title: Adjusting the Ground Truth Annotations for Connectivity-Based Learning
to Delineate
- Abstract summary: In this paper, we introduce a method that explicitly accounts for annotation inaccuracies.
We treat the annotations as active contour models that can deform themselves while preserving their topology.
This enables us to jointly train the network and correct potential errors in the original annotations.

- Abstract: Deep learning-based approaches to delineating 3D structure depend on accurate
annotations to train the networks. Yet, in practice, people, no matter how
conscientious, have trouble precisely delineating in 3D and on a large scale,
in part because the data is often hard to interpret visually and in part
because the 3D interfaces are awkward to use. In this paper, we introduce a
method that explicitly accounts for annotation inaccuracies. To this end, we
treat the annotations as active contour models that can deform themselves while
preserving their topology. This enables us to jointly train the network and
correct potential errors in the original annotations. The result is an approach
that boosts performance of deep networks trained with potentially inaccurate
annotations.

3D segmentation is a core problem in computer vision.
densely labeling 3D point clouds to employ fully-supervised training remains too labor intensive and expensive.
Semi-supervised training provides a more practical alternative, where only a small set of labeled data is given, accompanied by a larger unlabeled set.

We propose a new self-supervised method for pre-training the backbone of deep perception models operating on point clouds.
The core idea is to train the model on a pretext task which is the reconstruction of the surface on which the 3D points are sampled.
The intuition is that if the network is able to reconstruct the scene surface, given only sparse input points, then it probably also captures some fragments of semantic information.
