Improving Faint Object Detection for Space Situational Awareness with Variational Autoencoders
TL;DR
A deep-learning pipeline was developed to enhance the detection of faint moving objects in space imagery by automating star removal and background reconstruction. This method significantly improves the detectability of low signal-to-noise ratio objects in challenging environments like cislunar space.
✦ Why It Matters
Implement this pipeline to enhance faint object detection in your optical SSA projects today.
Key Takeaways
- Utilize Tiny-U-Net for effective star masking in SSA imagery.
- Apply astro-VAE for context-aware background reconstruction.
- Integrate this pipeline with existing detection algorithms.
- Test the method on real telescope data for validation.
How It Works
The pipeline employs Tiny-U-Net to create masks of stars in the imagery, allowing the astro-VAE to focus on reconstructing the background without the interference of fixed stellar sources. The astro-VAE uses partial convolutions to learn and inpaint the masked areas, effectively generating a clean background that enhances the visibility of faint moving objects.
