Cloud detection plays an essential role in meteorological research and has received considerable attention recent years. However, this issue is particularly challenging due to the diverse characteristics of clouds. In letter, a novel algorithm based on superpixel segmentation (SPS) proposed for cloud detection. our strategy, series superpixels could be obtained adaptively by SPS according We first calculate local threshold each then determine matrix whole image. Finally, can detected...
Although traditional bag-of-words model has shown promising results for action recognition, it takes no consideration of the relationship among spatio–temporal points; furthermore, also suffers serious quantization error. In this letter, we propose a novel coding strategy called context-constrained linear (CLC) to overcome these limitations. We first calculate contextual distance between local descriptors and each codeword by considering information. Then, using is adopted alleviate Our...

The Hot Universe Baryon Surveyor (HUBS) mission is proposed to study "missing" baryons in the universe. Unlike dark matter, baryonic matter made of elements periodic table, and can be directly observed through electromagnetic signals that it produces. Stars contain only a tiny fraction known present Additional are found diffuse (gaseous) form, or between galaxies, but significant has not yet been seen. latter (missing baryons) thought hiding low-density warm-hot ionized medium (WHIM), based...
Two kinds of Al/Zr (Al(1%wtSi)/Zr and Al(Pure)/Zr) multilayers for extreme ultraviolet (EUV) optics were deposited on fluorine doped tin oxide coated glass by using direct-current magnetron sputtering technology.
