Reducing the feature divergence of RGB and near-infrared images using Switchable Normalization [article]

Siwei Yang, Shaozuo Yu, Bingchen Zhao, Yin Wang
2021 arXiv   pre-print
Using the popular symmetric Kullback Leibler divergence measure, we show that our model can greatly reduce the divergence between RGB and near-infrared channels.  ...  Thus, we apply a Switchable Normalization block to our DeepLabV3 segmentation model to alleviate the feature divergence.  ...  In Fig. 2 , we show the feature divergence between RGB and NIR can be reduced by using IBN-Net.  ...

Electro-Optic Effects in Colloidal Dispersion of Metal Nano-Rods in Dielectric Fluid

Andrii Golovin, Jie Xiang, Heung-Shik Park, Luana Tortora, Yuriy Nastishin, Sergij Shiyanovskii, Oleg Lavrentovich
2011 Materials  
The electric field controls orientation and concentration of NRs and thus modulates the optical properties of the medium.  ...  Using gold (Au) NRs dispersed in toluene, we demonstrate electrically induced change in refractive index on the order of 0.1.  ...  The power flow near the electrode is bent towards the middle plane of the figure. The effect is the result of the reduced refractive index n near the central electrode.  ...
