Abstract We present an updated model for the extragalactic background light (EBL) from stars and dust, over wavelengths ?0.1–1000 ? m. This uses accurate theoretical stellar spectra, tracks evolution of star formation, mass density, metallicity, interstellar dust extinction emission in universe with redshift. Dust components are treated self-consistently, absorbed by reradiated infrared as thre...

Due to the deteriorated conditions of illumination lack and uneven lighting, performance traditional background modeling methods is greatly limited for surveillance nighttime video. To make under scene performs as well in daytime condition, we put forward a promising generation-based framework foreground surveillance. With pre-specified reference image frame, GAN based generation model, called ...
