Mind-Video is a cutting-edge AI tool designed to reconstruct high-quality videos from brain activity captured through continuous functional magnetic resonance imaging (fMRI) data. Developed by a team from the National University of Singapore and The Chinese University of Hong Kong, this tool extends the previous fMRI-Image reconstruction work known as Mind-Vis. Mind-Video employs a sophisticated two-module pipeline that bridges the gap between decoding static images and reconstructing dynamic video sequences from brain signals.
Major Highlights
- Uses continuous fMRI data to create high-quality videos.
- Employs a two-module pipeline: an fMRI encoder and a stable diffusion model.
- Utilizes unsupervised learning and spatiotemporal attention for feature extraction.
- Fine-tunes video generation with augmented stable diffusion models.
- Achieves high semantic accuracy, capturing motions and scene dynamics.
- Outperforms previous state-of-the-art approaches in video reconstruction.
- Leverages data from the Human Connectome Project.
- Demonstrates the dominance of the visual cortex in processing visual information.
- Showcased at NeurIPS 2023 for its significant contributions to neuroscience.
- Developed by experts Zijiao Chen, Jiaxin Qing, and Juan Helen Zhou.
