neurovc 0.1.0

Framework for Computer Vision setups in Neuroscience

🚧 Under Development

This project is still in an alpha stage. Expect rapid changes, incomplete features, and possible breaking updates between releases.

• The API may evolve as we stabilize core functionality.
• Documentation and examples are incomplete.
• Feedback and bug reports are especially valuable at this stage.

NeuroVC

Toolbox with utility functions for computer vision setups in neuroscience. The core module contains classes for motion magnification and camera io.
