L-Mind: A Multimodal Dataset for Neural-Driven Image Editing

This dataset is part of the NeurIPS 2025 paper: "Neural-Driven Image Editing", which introduces LoongX, a hands-free image editing approach driven by multimodal neurophysiological signals.

📄 Overview

L-Mind is a large-scale multimodal dataset designed to bridge Brain-Computer Interfaces (BCIs) with generative AI. It enables research into accessible, intuitive image editing for individuals with limited motor control or language abilities.

• Total Samples: 23,928 image editing pairs
• Participants: 12 subjects (plus cross-subject evaluation data)
• Task: Instruction-based image editing viewed and conceived by users

🧠 Modalities

The dataset features synchronized recordings of:

1. EEG (Electroencephalography): Captures rapid neural dynamics (4 channels: Pz, Fp2, Fpz, Oz).
2. fNIRS (Functional Near-Infrared Spectroscopy): Measures hemodynamic responses (cognitive load/emotion).
3. PPG (Photoplethysmography): Monitors physiological state (heart rate/stress).
4. Head Motion: 6-axis IMU data tracking user movement.
5. Speech: Audio instructions provided by users.
6. Visuals: Source Image, Target Image, and Text Instruction.

🚀 Applications

This dataset supports the training of neural-driven generative models (like LoongX) that can interpret user intent directly from brain and physiological signals to perform:

• Background replacement
• Object manipulation
• Global stylistic changes
• Text editing
