Using 4 residual modules as base network, then add SSD's extra layers.

The structure is same as ResNet10-SSD except its filter number. When filter number is larger than 32, reduce it by half.

Our iris dataset has 12800 training samples and 3200 test samples. Training on GTX1080Ti. Evaluate on Intel i5 CPU and GTX1080Ti GPU.
Speed test ResNet10+SSD(half) is faster than others.
| Network | [email protected] | Speed on Intel i5 CPU(ms) | Speed on GTX1080Ti(ms) | Input resolution |
|---|---|---|---|---|
| ResNet10+SSD | 1.0 | 20 | 13 | 640x480 |
| ResNet10+SSD(half) | 1.0 | 10 | 7 | 640x480 |
| MobileNet+SSD | - | 27 | 18 | 640x480 |
When set confidence threshold to 0.5 and set IoU threshold to 0.5, the accuracy is 100%.
On Intel i5 CPU, the average inference time is 20ms. On GTX1080Ti GPU, the average inference time is 13ms.

We just evaluate mobilenet_300x300_ssd_iter_3000.caffemodel. On Intel i5 CPU, the average inference time is 27ms. On GTX1080Ti GPU, the average inference time is 18ms. The speed is slower than ResNet10-SSD which has high accurracy on iris dataset, so we stop training.
