上海大学学报(英文版)/Journal Journal of Shanghai University(English Edition)
查看更多>>《Journal of Shanghai University》是在钱伟长校长的大力倡导和支持下于1997年6月创刊的。本刊由上海大学出版社出版,《上海大学学报》(英文版)编委会编辑, 上海大学期刊社发行。本刊设有“Reviews”,“Articles”,“Letters”,“Abstracts of Doctoral Dissertations”等栏目,报道范围涉及自然科学与工程技术的多种领域,主要有“应用数学和力学”,“信息技术”,“机电工程与自动化”,“材料科学与工程”等领域。 本刊重视学术论文的创新性。钱校长在本刊发刊词中把科研成果分为三类:第一类用新理论新方法解决新问题;第二类用新理论新方法解决老问题或用已有理论和方法解决新问题;第三类用已有理论和方法解决老问题。本刊将优先刊登第一类学术论文,也发表一些第二类学术论文,而不采用第三类论文。本刊只刊出未在正式刊物上公开发表过的研究论文。 本刊除刊登上海大学教师和研究生的最新研究成果外,也刊登其它高校及科研院所专家学者们的优秀学术论文,而且在论文的筛选和刊出上一视同仁。本刊尤其欢迎国家自然科学基金课题和国家“八六三”项目的研究论文以及海外留学生的研究论文,也欢迎资深学者的专题综述文章, 本刊也以“Letters”的形式报道学者们的阶段性研究成果。本刊主要向国外发行,向国外近20家文献检索刊物和数据库及近百所大学图书馆按期寄送。到目前为止,本刊已被国际多家重要检索刊物或数据库收录。它们是美国的“工程索引”(EI Page One),英国的“科学文摘”(SA-INSPEC),俄罗斯的“文摘杂志”(РЖ),日本的“科学技术文献速报”(CBST),美国的“剑桥科学文摘”(CSA),美国的“数学评论”(MR),美国的“应用力学评论”(AMR),德国的“数学文摘”(ZBI),美国的“化学文摘”(CA)等的收录期刊。本刊同时被国内4家全文数据库和多家专业文摘刊物收录。欢迎国内外专家学者投稿,有关投稿的具体要求见本刊征稿简则。本刊国内外公开发行, 可通过天津联合征订服务部、北京人天书店征订,也可直接向上海大学期刊社征订。

When depth maps are derived using existing depth estimation methods,the depth distortions will cause undesirable artifacts in the synthesized views.To solve this problem,a 3D video quality model base depth maps (D-3DV) for virtual view synthesis and depth map coding in the FTV applications is proposed.First,the relationships between distortions in coded depth map and rendered view are derived. Then,a precisely 3DV quality model based depth characteristics is develop for the synthesized virtual views.Finally,based on D-3DV model,a multilateral filtering is applied as a pre-processed filter to reduce rendering artifacts.The experimental results evaluated by objective and subjective methods indicate that the proposed D-3DV model can reduce bit-rate of depth coding and achieve better rendering quality.

    Non-reference virtual view quality evaluation of MVD

    查看更多>>摘要:The quality of virtual view based on multi-view video (MVD) plus depth format is often evaluated by PSNR or subjectively judged.However,due to synthesizing arbitrary view images,the virtual view images mostly have no reference images and are only assessed using non-reference.Virtual view images synthesized by depth estimation reference software (DERS) and view synthesis reference software (VSRS) often accompanied with blockiness and other distortions on the edge.In addition,matching level for the depth map and the corresponding texture maps of left and right views also affects the quality of the virtual view.This paper compares the edge similarity of the depth and the corresponding texture maps which generate the intermediate virtual view and combined with the virtual view's blockiness which causing blur to evaluate the quality of the virtual view.Experiment results show that the proposed method can reflect the quality of the virtual view better.
