Hyperspectral Image Classification Algorithm Based on Saliency Profile
Xuan Hu, and Qikai Lu
Generally, the objects in an image have complex shapes and sizes. Therefore, it is difficult for the existing morphological features to completely describe the significant spatial information of the image. Hence, a morphological saliency profile is developed in this study based on the saliency measure. The grayscale an

Lens-Free Imaging Method Based on Generative Adversarial Networks
Chao Zhang, Tao Xing, Zizhen Liu, Haokun He, Hua Shen, Yinxu Bian, and Rihong Zhu
Lens-free inline holography contains zero-order image noise and twin image noise. Methods based on the Fresnel diffraction model can suppress these noise, but require many lens-free images. To resolve this problem, this paper proposes a lens-free imaging method based on generative adversarial networks (GAN). First, the

Iterative Extrapolation Method to Expand Dynamic Range of Shack-Hartmann Wavefront Sensors
Yanna Han, Xinqi Hu, and Bing Dong
The Shack-Hartmann wavefront sensor (SHWS) generally requires that the focal spot of each microlens must remain in its corresponding sub-aperture area so that it is easy to decide the mapping relationship of spots and subapertures. We present a software-based recognition method, i.e., an iterative extrapolation method,

A Three-Dimensional Measurement Method Based on Multiple Reflected Images
Shunyu Xu, and Xiao Xu
When multi-view structured light is used for three-dimensional measurement of metallic objects, the structured light images obtained by each camera exhibit obvious differences because the reflected light intensity significantly changes with the angle; thus, the degree of matching of images is reduced. At some locations

Optically Pumped 4 μm CW HBr Gas Laser Based on Hollow-Core Fiber
Zhiyue Zhou, Hao Li, Yulong Cui, Wei Huang, and Zefeng Wang
An optically pumped mid-infrared HBr gas laser based on hollow-core fiber (HCF) is reported. A tunable narrow linewidth 2 μm continuous-wave thulium-doped fiber amplifier is used to pump a 4.4 m anti-resonance hollow-core fiber filled with low-pressure HBr gas. When the seed wavelength is precisely tuned to the R(2) ab

Semi-Global Stereo Matching of Remote Sensing Images Combined with Speeded up Robust Features
Yangping Wang, Anna Qin, Qi Hao, and Jianwu Dang
The semi-global stereo matching (SGM) for remote sensing images is sensitive to noise and produces fringes in the areas with discontinuous disparity and weak texture, resulting in a low matching rate. An SGM algorithm for remote sensing images combined with speeded up robust features (SURF) is proposed herein. First, S
