Cameras in cities can help security departments track the whereabouts of targets. Manual methods and traditional image processing methods have low accuracy and slow efficiency, and supervised learning requires a large amount of labeled data and is less robust. However, unlabeled data in a large number of application scenarios can be obtained through surveillance video.
Optical remote sensing images are subject to various noisy images during the process of acquisition and transmission, which blur the details such as edge texture and reduce image quality. The remote sensing images without clear and high-quality must be pre-processed with noise reduction.
Optical frequency comb, a Nobel Prize-winning device, can emit numerous evenly spaced and phase-coherent laser lines simultaneously. Besides metrology, attosecond science, and optical communication, frequency comb has recently become an extremely powerful tool for high-precision spectroscopy.
Electro-optical systems play a critical role in numerous applications, such as remote sensing, space exploration, laser communication, aerial imaging, and other pertinent domains. High-accuracy optical beam stabilization of large-aperture electro-optical systems remains a challenging task, especially under complex imaging environments.
Rapid identification of marine microorganisms is critical in marine ecology, and Raman spectroscopy is a promising means to achieve this. Single cell Raman spectra contain the biochemical profile of a cell, which can be used to identify cell phenotype through classification models.
Full-color flexible micro-LED devices are hot spots in the fields of wearable devices and vehicle displays. In previous studies, only blue and violet flexible micro-LEDs have been fabricated. In order to realize full-color display based on flexible micro-LEDs, it is necessary to study the method of realizing full-color display using color conversion technology.
