Deep Domain Adaptation Based Video Smoke Detection using Synthetic Smoke Images

no code implementations31 Mar 2017 Gao Xu, Yongming Zhang, Qixing Zhang, Gaohua Lin, Jinjun Wang

Considering that the appearance gap (dataset bias) between synthetic and real smoke images degrades significantly the performance of the trained model on the test set composed fully of real images, we build deep architectures based on domain adaptation to confuse the distributions of features extracted from synthetic and real smoke images.
