DynaFilter: Cloud-driven Dynamic Filtering for Satellite Edge Intelligence

Jul 14, 2026

DynaFilter is a dynamic filtering technique that allows satellite edge devices to perform selective region-of-interest inference directly in the compressed domain, eliminating the need for full decompression. The method leverages low-level compression features to identify and transmit only relevant data, reducing the pixel data required for decoding by 1.6x-7.1x for images and achieving up to 92.0% bandwidth savings for video streams compared to state-of-the-art baselines. Additionally, DynaFilter decreases energy consumption by 43.1-88.6% and speeds up inference latency by 1.6x-3.0x on target devices.

Why it matters: This technique enables more efficient and practical remote sensing on satellite edge systems by significantly reducing bandwidth, energy use, and latency.
