Optical waves can be described by intensity and phase. However, optical waves oscillate too fast for detectors to measure anything but time-averaged intensities. This is unfortunate since the phase can reveal important information about the object. T

Tracking a spacecraft with the satellite-based imaging system is an essential task to on-orbit servicing, status monitoring, and visual navigation in the field of remote sensing. Tracking-by-segmentation uses the silhouette to describe the target spa

A phase-sensitive optical time-domain reflectometric (Φ-OTDR) system based on the direct detection is demonstrated. It uses amplitude difference and two-dimensional Fourier transform method to extract the vibration information with a frequency respo

In this paper, we address the multiframe super resolution problem from a set of degraded, under-sampled, shifted and rotated low resolution images to obtain a high resolution image using the variational Bayesian methods. In the Bayesian framework a p

With the development of modern technology, especially the development of information technology at high speed, the ultraviolet early warning system plays an increasingly important role. In the modern warfare, how to detect the threats earlier, preven
