This article describes a novel approach for enhancing the three-dimensional(3D)point cloud reconstruction for light field microscopy(LFM)using U-net architecture-based fully convolutional neural network(CNN).Since the directional view of the LFM is limited,noise and artifacts make it difficult to reconstruct the exact shape of 3D point *** existing methods suffer from these problems due to the self-occlusion of the *** manuscript proposes a deep fusion learning(DL)method that combines a 3D CNN with a U-Net-based model as a feature *** sub-aperture images obtained from the light field microscopy are aligned to form a light field data cube for preprocessing.A multi-stream 3D CNNs and U-net architecture are applied to obtain the depth feature fromthe directional sub-aperture LF data *** the enhancement of the depthmap,dual iteration-based weighted median filtering(WMF)is used to reduce surface noise and enhance the accuracy of the *** a 3D point cloud involves combining two key elements:the enhanced depth map and the central view of the light field *** proposed method is validated using synthesized Heidelberg Collaboratory for Image Processing(HCI)and real-world LFM *** results are compared with different state-of-the-art *** structural similarity index(SSIM)gain for boxes,cotton,pillow,and pens are 0.9760,0.9806,0.9940,and 0.9907,***,the discrete entropy(DE)value for LFM depth maps exhibited better performance than other existing methods.

Substrate temperature dependent studies on properties of chemical spray pyrolysis deposited CdS thin films for solar cell applications

Journal of Semiconductors 2017年第2期38卷 5-14页

Thin films of CdS have been prepared by chemical spray pyrolysis by spraying precursor solution directly onto soda lime glass（SLG） substrates. Influence of substrate temperature on structural, optical, morphological and electrical properties have been investigated by using various techniques such as low angle X-ray diffraction（XRD）, Raman spectroscopy, X-ray photoelectron spectroscopy（XPS）, field emission scanning electron microscopy（FESEM）, atomic force microscopy（AFM）, transmission electron microscopy（TEM）, UV–visible spectroscopy photoluminescence（PL） spectroscopy etc. Formation of CdS has been confirmed by low angle XRD,Raman spectroscopy and XPS analysis. XRD pattern showed that CdS films are polycrystalline, have hexagonal structure and prefer orientation of crystallites shifts from（101） to（002） with increase in substrate *** spectroscopy revealed that exciton-phonon coupling depends on substrate temperature and hence on crystallite size. Optical band gap increased from 2.43 to 2.99 eV when substrate temperature increased from 325 to 475 ℃. Transmittance of the film also showed an increasing trend from 52% to 80% with increase in substrate temperature. Such high band gap and transmittance values of CdS films prepared at 475℃ make it a useful window material in CdS/CdTe and CdS/Cu_2S heterojunction solar cells.
