Turned out to be pretty easy to integrate the ssd_mobilenet_v2_coco model compiled for the Intel NCS 2 into rt-ai Edge. Since it doesn’t use the GPU, I was able to run this and the YOLOv3 SPE on the same machine which is kind of amusing – one YOLOv3 instance tends to chew up most of the GPU memory, unfortunately, so the GPU can’t be shared. I would have liked to have run YOLOv3 on the NCS 2 for direct comparison but could not. The screen capture above shows the MediaView SPE output for both detectors running on the same 1280 x 720 video stream.
This is the design and it is showing the throughput of each detection SPE – 14 fps for the GTX 1080 ti YOLO and 9 fps for the NCS 2 based SSD. Not exactly a fair comparison, however, but still interesting. It would be much better if I had the same model running using a GPU of course. Right now, the GPU-based SPE that can run ssd_mobilenet_v2_coco (and similar models) is Python based and that (not surprisingly) runs a fair bit slower than the compiled C++ versions I am using here.
