Separate in Latent Space: Unsupervised Single Image Layer Separation
Proceedings of the AAAI Conference on Artificial Intelligence, 2020Co-Authors: Yunfei LiuAbstract:Many real world vision tasks, such as reflection removal from a Transparent Surface and intrinsic image decomposition, can be modeled as single image layer separation. However, this problem is highly ill-posed, requiring accurately aligned and hard to collect triplet data to train the CNN models. To address this problem, this paper proposes an unsupervised method that requires no ground truth data triplet in training. At the core of the method are two assumptions about data distributions in the latent spaces of different layers, based on which a novel unsupervised layer separation pipeline can be derived. Then the method can be constructed based on the GANs framework with self-supervision and cycle consistency constraints, etc. Experimental results demonstrate its successfulness in outperforming existing unsupervised methods in both synthetic and real world tasks. The method also shows its ability to solve a more challenging multi-layer separation task.

Flexible and Transparent Surface acoustic wave microsensors and microfluidics
Procedia Engineering, 2015Co-Authors: Ji Kui Luo, Xing-li He, Wei-peng Xuan, Jin-kai Chen, Hao Jin, Jian Zhou, Yang Xu, Wen Bo Wang, Shurong DongAbstract:This paper reports the development of flexible and Transparent (FT) Surface acoustic wave (SAW) technology, and FT-SAW based various sensors (temperature, humidity, UV-light and strain) and microfluidics on polymer and glass. The devices on polymers have the Rayleigh and Lamb resonances, while those on glass have the Rayleigh mode only. All the modes have large signal amplitudes. FT-SAW based sensors show excellent sensitivities, comparable to or better than those on rigid substrates. The temperature sensitivity of the sensors on PI is more than one order of magnitude larger than those on rigid substrates. The humidity sensitivity can be further increased significantly by using a graphene oxide (GO) sensing layer. All types of the sensors have excellent stability and reliability. FT-SAW also demonstrated very good capability to deliver microfluidic functions such as acoustic streaming and particle concentration etc. The results demonstrated the FT-SAW have great potential for applications.

Transparent Surface acoustic wave devices on zno glass using al doped zno as the electrode
IEEE Electron Device Letters, 2013Co-Authors: Jian Zhou, Wei-peng Xuan, Hao Jin, Shurong Dong, Wen Bo Wang, Qi Zhu, Miao De Wang, Ji Kui LuoAbstract:This letter reports the design of Transparent Surface acoustic wave (SAW) resonators using aluminum-doped ZnO (AZO) as the Transparent electrode on ZnO/glass substrates. SAW devices with a resonant frequency up to 204.4 MHz and signal amplitude up to 25 dB were obtained with transparency above 80%. An AZO layer of more than 250 nm is needed to minimize the series resistance of the electrode to achieve reasonable performance. Temperature sensing showed that they have a temperature coefficient of frequency of ~50 ppm/K. This demonstrates the great potential of Transparent SAW devices for widespread applications, as such devices are one the of building blocks of electronics, sensors, and microsystems.
