Comparison of the characteristics of different algorithms.

Algorithms	Network structure	Backbone network	Feature extraction capability
The proposed method	One-stage	MobileNetv2	Multiscale feature extraction
Tiny-YOLOv3	One-stage	7-layer conv + Max	The ability of deep feature extraction is poor.
MobileNetv2-YOLOv3	One-stage	MobileNetv2	The ability of deep feature extraction is poor.
MobileNetv2-SSD	One-stage	MobileNetv2	The ability of deep feature extraction is poor.
Faster R-CNN	Two-stage	ResNet	The accuracy outperforms some of the one-stage detectors, but the speed is low.
