Dataset Description
This dataset accompanies the research paper Pre-Generating Multi-Difficulty PDE Data For Few-Shot Neural PDE Solvers (under review at ICLR 2026). It contains systematically generated 2D incompressible Navier-Stokes fluid flow simulations designed to study difficulty transfer in neural PDE solvers.The key insight: by pre-generating many low and medium difficulty examples and including them… See the full description on the dataset page: https://huggingface.co/datasets/sage-lab/PreGen-NavierStokes-2D.transplat_dl3dv_2dMode_1Sub2D_FalseAlphadl3dv_2dMode_1Sub2D_TrueAlpha_fromRe10KPretrainedqwen35-2d-grounding-sfthipsc_2dSTS-2D-Tooth

KITTI 2D Object Detection (Lance Format)
A Lance-formatted version of the KITTI 2D Object Detection benchmark, sourced from nateraw/kitti so no manual signup or download from cvlibs.net is required. Each row is a single driving frame with inline JPEG bytes, the full set of 2D and 3D object annotations stored as parallel per-object lists, plus a cosine-normalized OpenCLIP ViT-B-32 image embedding — all available directly from the Hub at… See the full description on the dataset page: https://huggingface.co/datasets/lance-format/kitti-2d-detection-lance.2D_Video_Game_Cartoon_Character_Sprite-Sheets

Experimental composition of 76 cartoon art-style video game character spritesheets. Resized to 512x512, mixed variation of animation styles.
Dataset Description
All images editted using Tiled image editting software as most assets are typically downloaded individually and not in sequence. I compiled each animation sequence into one img to display animations frame-by-frame evenly distributed across some common… See the full description on the dataset page: https://huggingface.co/datasets/mgane/2D_Video_Game_Cartoon_Character_Sprite-Sheets.cellmap-2d
CellMap 2D
This dataset contains all 2D slices from the EM volumes used in the CellMap segmentation challenge.
The dataset contains all x, y, z slices obtained from a total of 289 3D EM volume crops (the crops come from 22 different samples),
together with their corresponding labeled segmentation masks.
The slices were prepared and pushed to the HF datasets Hub with
this script.

Instance-segmentation dataset of small tabletop objects (cork, pompom,
lighter) captured with an Intel RealSense camera. It is the data behind an
RGB-D perception and grasping pipeline: 2D YOLO instance segmentation, lifting
masks to 3D, and base-frame pose estimation for robot picking.

OpenOrganelle 2D
This dataset contains a large collection of 2D slices from the EM volumes on HHMI Janelia's OpenOrganelle data repository.
The dataset contains a total of ~2.67 million x, y, and z slices obtained from 79 different 3D EM volumes on OpenOrganelle.
Notes
The following volumes on OpenOrganelle are missing from the current repository because they were too large to process and store here:

SAM3 low-Dice 2D datasets for nnU-Net
Private research export of two small 2D datasets on which the balanced-finish
SAM3 LoRA validation Dice was below 0.5. The purpose is to test whether a
dataset-specific nnU-Net can fit these data and to distinguish data/training
limitations from inference bugs.

Cleaned KITTI Dataset
Overview
This repository provides a cleaned version of the KITTI 2D Object Detection Benchmark. The dataset was curated as part of the research project:
Analyzing Training-Free Corruption Detection for Object Detection Datasets
The goal of the cleaning process was to identify potential annotation inconsistencies using a training-free feature-space based corruption detection approach.
The original KITTI annotation format and folder structure… See the full description on the dataset page: https://huggingface.co/datasets/Chris1095/clean-kitti-2d-object-detection.eval-pack-wjt-of-my-project-ir4dht-2dd66d78
