A Lightweight Dangerous Liquid Detection Method Based on Depthwise Separable Convolution for X-Ray Security Inspection

Algorithm 1

Semiautomatic labeling method.

	Input: The dual-energy X-ray dataset, the lightweight object location network and the confidence score threshold T
	Output: The dual-energy X-ray dataset with labels and the trained lightweight object location network
(1) Train with Ul
