Questions & Answers

Q: How does Epsilon Photography enhance the spatial resolution of photos?

Epsilon Photography uses techniques like super resolution, where multiple images are captured with slight sensor movements to increase spatial resolution.

Q: What is the purpose of creating panoramas over time in Epsilon Photography?

Creating panoramas over time allows for wider field of view and higher resolution by capturing and stitching together multiple images taken at different camera positions.

Q: What are the challenges faced in Epsilon Photography?

Challenges include issues with calibration, color correction, high dynamic range adjustments, and exposure variations when combining multiple images or sequences.

Q: How does Epsilon Photography improve the temporal resolution of photos?

Epsilon Photography can increase the temporal resolution by using multiple cameras with lower frame rates, which are combined to create a higher frame rate output.

Summary & Key Takeaways
