Color When It Counts: Grayscale-Guided Online Triggering for Always-On Streaming Video Sensing

arXiv CS.AI

ArXi:2603.22466v1 Announce Type: cross Always-on sensing is essential for next-generation edge/wearable AI systems, yet continuous high-fidelity RGB video capture remains prohibitively expensive for resource-constrained mobile and edge platforms. We present a new paradigm for efficient streaming video understanding: grayscale-always, color-on-demand. Through preliminary studies, we discover that color is not always necessary. Sparse RGB frames suffice for comparable performance when temporal structure is preserved via continuous grayscale streams.
