Abstract

fetched live from OpenAlex

The dataset introduced in "PointGauss: Point Cloud-Guided Multi-Object Segmentation for Gaussian Splatting" DesktopObjects-360, a benchmark specifically designed for 3D segmentation for radiance field (3DGS and NeRF). The key features include: 1. The dataset provides COLMAP format data, making it directly applicable to 3DGS and NeRF modeling. 2. 3D Instance annotations are available for Gaussian models. 3. Pixel-level instance segmentation annotations are provided for 2D images. 4. The instance IDs for 2D and 3D objects remain consistent across different viewpoints. The dataset contains a total of 3,364 multi-view images with fine-grained 2D and 3D instance annotations. Each scene includes 7--10 object instances (56 annotated 3D instances in total), covering common desktop items under varying layouts and occlusions. To support instance segmentation tasks, we provide 26,042 pixel-accurate 2D instance masks across all scenes, with an average of 465 masks per 3D instance, ensuring dense and consistent multi-view correspondence. The DesktopObjects-360 dataset is organized in a hierarchical directory structure, with a root folder containing six subdirectories (Desk1 through Desk6) and one PointCloud.7z. Each Desk folder follows a consistent organization scheme, as exemplified by Desk1 which contains subfolders for 1. test data (Desk1_test), 2. original images (images), 3. segmentation masks (mask), 4. visualized masks (mask_visualize), 5. pretrained model annotations (annotated\_pretrained_model(2dgs)), 6. and a class label file (class.txt). In addition, we also provide pre-trained 2D Gaussian Splatting (2DGS) models with annotations for 10 scenes from the Nerds360 dataset.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
