基于多尺度局部自相似性和邻域嵌入的超分辨率算法研究

第三十九届中国控制会议

作者： Xiaoxing Ren Dewei Li Yugeng Xi lulu pan Haibin Shao Department of Automation Shanghai Jiao Tong University Key Laboratory of System Control and Information Processing Ministry of Education of China

We consider the distributed optimization problem on signed networks. Each agent has a local function which depends on a subset of the components of the variable and is subject to a local constraint set. A primal-dual algorithm with fixed step size is proposed. The algorithm ensures that the agents’ estimates converge to a subset of the components of an optimal solution or its opposite. Note that each component of the variable is allowed to be associated with more than one agents, our algorithm guarantees that those coupled agents achieve bipartite consensus on estimates for the intersection components. Numerical results are provided to demonstrate the theoretical analysis.

多尺度局部自相似性是指同一幅图像中存在相同尺度或不同尺度的相似子块,这种图像局部结构自相似性广泛存在于自然图像中。提出了一种基于多尺度局部自相似性结合邻域嵌入的单幅图像超分辨率算法,该算法不依赖于外界图像,仅仅在原始图像的局部子窗口中搜索目标图像块的相似子块,并结合邻域嵌入算法,进一步提高参与重建的图像块与目标图像块的相似性程度。实验结果表明,与双三次插值与传统邻域嵌入算法相比,新算法在保证算法效率的前提下,能有效提升超分辨图像的重建质量。

谈及中国电影史上的戏曲改编电影,《五女拜寿》(陆建华,1984)是绕不开的一座里程碑。影片改编自浙江小百花越剧团同名立团剧目,讲述了明朝嘉靖年间,户部侍郎杨继康做寿,五个女儿和女婿前来贺喜,养女三春及女婿邹应龙因家境清寒而受杨夫人驱赶。尔后,杨继康因不满内阁首辅严嵩专权而遭迫害,五个女儿中只有三春愿意收留二老。随着邹应龙高中状元,严嵩被贬,杨继康恢复名誉,五个女儿再来贺寿。影片通过此事前后众人的不同表现,讽刺了趋炎附势的小人行径,也歌颂了正直高尚的真挚情感。影片一经上映便好评如潮,不仅获得了第五届中国电影金鸡奖“最佳戏曲片奖”、中国广播电影电视部优秀影片奖,更斩获第七届长春电影制片厂“小百花”奖“优秀戏曲片”和“优秀戏曲片女主角”。

在类石墨烯结构的Bi2Se3拓扑绝缘体夹层中化学掺杂Cu原子形成CuxBi2Se3。Cu含量为12at%~15at%,温度为3.8~4.2K时,CuxBi2Se3块体内呈现超导电性,称之为拓扑超导体。CuxBi2Se3拓扑超导体是一种时间反演不变超导体,体电子态为满带能隙超导态,表面为无能隙Andreev束缚态,并且由于强自旋-轨道耦合效应具有三维狄拉克能带结构。科学家在CuxBi2Se3拓扑超导体中捕捉到了长期以来寻找的零质量零电荷的马拉约那费米子。马拉约那费米子不被附近的粒子、原子吸引或排斥,强烈对抗无序和杂质,这种容错特性将有效保护脆弱的量子态不受侵害,为将来自旋量子学和量子计算机的实现提供新平台。本文针对CuxBi2Se3拓扑超导体这一新型量子材料论述其理论和实验研究进展,然后结合材料科学学科特征论述CuxBi2Se3掺杂特性和反位缺陷形成特征,提出通过控制反位缺陷浓度和合理掺杂提高CuxBi2Se3的物理和化学性能的理论。

变异系数和基尼系数的计算结果显示,2019年我国高校毕业生的省域均衡性要优于美国,硕士毕业生的省域均衡性有所改善,但博士毕业生的省域差异显著且更为不均衡。我国省域高校毕业生总量与人口、地区生产总值高度相关,省域硕士毕业生次之,而省域博士毕业生数量与人口不相关、与产值弱相关。使用九宫图对我国省域硕士、博士毕业生与人口和产值的关系做进一步分析和比较。建议要服务战略需求,加强统筹协调,优化资源配置,科学比较分析,建设高质量研究生教育体系。
