Multi-information online detection of coal quality based on machine vision
TL;DR: An exploratory study employing a bench-scale approach to detect the multi-information of coal quality online by machine vision simultaneously, including particle size distribution, density distribution, the ash content of each density fraction, and the total ash content.
Proceedings ArticleDOI
Competitive Voting-based Multi-class Prediction for Ore Selection
TL;DR: A competitive voting method to improve the multi-class prediction accuracy of ores in machine vision-based sorting system by combining the classification advantages of various machine learning methods is proposed.
Proceedings ArticleDOI
An Empirical Study Towards SAR Adversarial Examples
TL;DR: Zhang et al. as mentioned in this paper analyzed the distribution characteristics of SAR adversarial examples (AEs) in both output space and feature space by transferring optical attacks and proposed a generation method of SAR AEs with regional constraint.
Journal ArticleDOI
Energy-Based Adversarial Example Detection for SAR Images
TL;DR: This work proposes an energy-based adversarial detector, which requires no modification to a pretrained model, and significantly boosts the detection performance against SAR AEs with region-constrained perturbation.
