OHB Hellas Contributions
OHB Hellas is the Prime Contractor for OrbitalCADENCE, a revolutionary content-aware algorithm that applies selective lossy compression. Our innovation lies in the “Intelligence-First” approach:
- Classification: An on-board CNN identifies Areas of Interest (AoI) such as land cover or vessel detection.
- Selective Compression: Areas of interest are compressed at low ratios (e.g., CR=4), while non-critical areas (clouds) are compressed at high ratios (e.g., CR=16).
- VQ-VAE Architecture: We utilize a Vector Quantized Variational AutoEncoder to transform high-dimensional data into a lower-dimensional latent space.
