色域压缩是大色域向小色域进行转换时保持色彩信息的关键技术。经典算法虽计算快速,但处理结果缺乏细节且没有考虑人眼的感知特性,难以满足人们对色彩品质不断提升的要求。迭代算法处理效果更佳,但极其耗时,无法投入实际应用。针对上述... 详细信息

色域压缩是大色域向小色域进行转换时保持色彩信息的关键技术。经典算法虽计算快速,但处理结果缺乏细节且没有考虑人眼的感知特性,难以满足人们对色彩品质不断提升的要求。迭代算法处理效果更佳,但极其耗时,无法投入实际应用。针对上述问题,提出了轻量化的深度色域压缩方法,该方法可在逼近迭代算法计算效果的同时保持接近经典算法的速度。为色域压缩算法设计了LightGCNet模型,该网络中的双层卷积由DSC与DW卷积组合而成,相比常规U-Net,参数量与计算复杂度急剧降低。为进一步提高模型先验性,将预训练得到的DW卷积中多个核通道进行重聚焦操作以建立联系,最终权重由重聚焦权重和预训练权重组成。针对色相、明度、彩度这三个色彩属性,设计了色域压缩专用的损失函数。该函数不仅考虑了像素级损失,而且融合了图像感知损失,并联合色彩属性的多尺度信息进行加权,解决了深度色域压缩过程中细节丢失的问题。基于迭代算法生成标签以训练网络,联合学习目标色域特征与图像信息,实现了与迭代算法相当的效果。实验结果表明:该方法与业界经典的SGCK算法相比,iCID值降低了17.08%,SSIM值提高了5.30%。相比常规U-Net模型,LightGCNet参数量减少了82.96%,乘加次数从8.5GFLOPs大幅下降至2.2GFLOPs,使改良模型更适于低端设备部署。该模型在CPU上处理单幅512×512图像仅需0.208s,计算时间比迭代类算法减少99.92%。

海上风机是低碳可持续能源的重要战略选择之一,其地震安全性问题是急需解决的重要课题。将近海单桩式风机三维地震响应问题看作波动散射问题,结合人工边界条件实现海域场地的波动输入,并基于广义饱和多孔介质统一计算框架,发展了一套海水-饱和海床-风机耦合作用高效分区分析方法,实现了综合考虑土-结构相互作用效应和流固耦合效应的近海单桩式风机三维地震响应分析,并分析了海水深度、海床波速和地震波入射角度对近海单桩式风机地震响应的影响。分析结果表明,海水深度和海床剪切波速的变化,一方面会改变自由场,另一方面会改变海域场地-风机体系的自振特性,从而影响风机结构的地震反应。当海水增加到某深度时,体系自振频率与地震波输入频率接近时,风机的地震响应会急剧增大;海床剪切波速对塔底弯矩的影响要比对位移的影响大;当入射角度增大时,塔顶水平向位移和加速度以及塔底弯矩均有不同程度的减小,塔顶竖向位移和加速度均有不同程度的增大。本文没有考虑海床和风机的非线性,考虑非线性时的影响规律需进一步研究。

近几年，东南亚和非洲原始森林遭受了掠夺性的砍伐，造成了进口原木资源日渐匮乏，特别是年底发生的印度洋海啸大灾难更是雪上加霜。为了满足国内市场的需求，一些进口商纷纷把目光瞄准了南美洲丰富的林木资源，开始从圭亚那、苏里南、玻利维亚等国家和地区进口原木和板材。相对南洋材和非洲材，国内用户对南美材特别是原木还是比较陌生的，某些不法外商就钻了这个空子，来了个“诈你没商量”。

Rare earth metal-organic frameworks (RE-MOFs) have drawn wide attention owing to diverse network structures and various application ***,due to the unpredictable formation of the nodes,it is still challenging to design novel RE-MOFs.A novel versatile strategy was developed employing a RE-acetate complex (RE2(CH3COO)6·4H2O) as a precursor to construct RE-MOFs.2D RE-MOFs (RE-DBP) and 3D RE-MOFs (RE-TCPP) could be obtained by using dicarboxylic porphyrin ligands H2DBP and tetracarboxylic porphyrin ligands H2TCPP,*** RE-MOFs were further synthesized to verify the universality of the *** crystalline RE-MOFs could also be prepared at room temperature via the developed strategy,which could significantly promote large-scale preparation and practical application of *** proof of the concept,the performance of porphyrin-based RE-MOFs was investigated in the photocatalytic cycloaddition of CO2with *** the RE-DBP(Co) MOFs,Tb-DBP(Co) exhibited the best photocatalytic performance,which was also greater than that of the corresponding 3D MOF Tb-TCPP(Co) due to the optimal 2D structure and thus the accelerated photogenerated charge separation and transfer *** work not only provides a novel versatile strategy to design and develop RE-MOFs,but also proposes a promising approach for the potential bulk production of RE-MOFs at room temperature.
