Low dynamic range(LDR)images captured by consumer cameras have a limited luminance *** the conventional method for generating high dynamic range(HDR)images involves merging multiple-exposure LDR images of the same scene(assuming a stationary scene),we introduce a learning-based model for single-image HDR *** input LDR image is sequentially segmented into the local region maps based on the cumulative histogram of the input brightness *** the local region maps,SParam-Net estimates the parameters of an inverse tone mapping function to generate a pseudo-HDR *** process the segmented region maps as the input sequences on long short-term ***,a fast super-resolution convolutional neural network is used for HDR image *** proposed method was trained and tested on datasets including HDR-Real,LDR-HDR-pair,and *** experimental results revealed that HDR images can be generated more reliably than using contemporary end-to-end approaches.

Flowering is the primary stage of the plant developmental transition and is tightly regulated by environmental factors such as light and ***,the mechanisms by which temperature signals are integrated into the photoperiodic flowering pathway are still poorly ***,we demonstrate that HOS15,which is known as a GI transcriptional repressor in the photoperiodic flowering pathway,controls flowering time in response to low ambient *** 16℃,the hos15 mutant exhibits an early flowering phenotype,and HOS15 acts upstream of photoperiodic flowering genes(GI,CO,and FT).GI protein abundance is increased in the hos15 mutant and is insensitive to the proteasome inhibitor ***,the hos15 mutant has a defect in low ambient temperature-mediated GI degradation,and HOS15 interacts with COP1,an E3 ubiquitin ligase for GI *** analyses of the hos15 cop1 double mutant revealed that repression of flowering by HOS15 is dependent on COP1 at 16℃.However,the HOS15-COP1 interaction was attenuated at 16℃,and GI protein abundance was additively increased in the hos15 cop1 double mutant,indicating that HOS15 acts independently of COP1 in GI turnover at low ambient *** study proposes that HOS15 controls GI abundance through multiple modes as an E3 ubiquitin ligase and transcriptional repressor to coordinate appropriate flowering time in response to ambient environmental conditions such as temperature and day length.
