I wanted to share a project I have been collaborating on with Soumik 1.
We take the problem of segmenting 3D point clouds that are important for modeling geometric properties from data. Today, we are delighted to open-source our repository 4 that implements the PointNet [1] model family for this purpose. We provide TensorFlow implementations with full support for TPUs and distributed training with mixed-precision (for GPUs). We provide models pre-trained on the four categories of the ShapeNet core dataset [2]. Here’s also a blog post 2 we have prepared to make it easier for getting started.
