- Abstract summary: We introduce an approach for selecting objects in neural volumetric 3D representations, such as multi-plane images (MPI) and neural radiance fields (NeRF)
Our approach takes a set of foreground and background 2D user scribbles in one view and automatically estimates a 3D segmentation of the desired object, which can be rendered into novel views.

- Abstract: We introduce an approach for selecting objects in neural volumetric 3D
representations, such as multi-plane images (MPI) and neural radiance fields
(NeRF). Our approach takes a set of foreground and background 2D user scribbles
in one view and automatically estimates a 3D segmentation of the desired
object, which can be rendered into novel views. To achieve this result, we
propose a novel voxel feature embedding that incorporates the neural volumetric
3D representation and multi-view image features from all input views. To
evaluate our approach, we introduce a new dataset of human-provided
segmentation masks for depicted objects in real-world multi-view scene
captures. We show that our approach out-performs strong baselines, including 2D
segmentation and 3D segmentation approaches adapted to our task.

Segmentation [26.726658200149544]
We propose ''Implicit Ray-Transformer (IRT)'' based on Implicit Neural Representation (INR) for RS scene semantic segmentation with sparse labels.
The proposed method includes a two-stage learning process. In the first stage, we optimize a neural field to encode the color and 3D structure of the remote sensing scene.
In the second stage, we design a Ray Transformer to leverage the relations between the neural field 3D features and 2D texture features for learning better semantic representations.

ONeRF is a method that automatically segments and reconstructs object instances in 3D from multi-view RGB images without any additional manual annotations.
The segmented 3D objects are represented using separate Neural Radiance Fields (NeRFs) which allow for various 3D scene editing and novel view rendering.

We propose to leverage both the global and local features to form an expressive 3D representation.
To synthesize a novel view, we train a multilayer perceptron (MLP) network conditioned on the learned 3D representation to perform volume rendering.
Our method can render novel views from only a single input image and generalize across multiple object categories using a single model.
