Researchers have developed DynaFilter, a novel technique for satellite edge intelligence that addresses bandwidth limitations by performing inference directly within compressed image and video data. This method avoids full decompression, instead leveraging correlations between low-level compression features like JPEG DC coefficients and motion vectors with high-level semantic queries. DynaFilter enables edge devices to identify and transmit only relevant regions of interest, significantly reducing data volume by up to 7.1x for images and achieving 92.0% bandwidth savings for video streams. The technique also leads to substantial energy savings and faster inference latency. AI
