"single-pixel detector, efficient and robust multi-object detection directly from few 2D measurements... heavy communication load, high computing overhead and low perception rate existing visual perception systems including driving... single-pixel object detection (SPOD) object detection accuracy 80%... transformer-based encoder extract high-dimensional features fed into  multi-scale attention network-based decoder outputs class, location and size... sampling rate 5% spatial light modulation 0.016 seconds"
