Specular highlight usually causes serious information degradation,which leads to the failure of many computer vision *** have proposed a novel bifurcated convolution neural network to tackle the problem of high reflectivity image information degradation.A two-stage process is proposed for the extraction and elimination of the specular highlight features,with the procedure starting at a coarse level and progressing towards a finer level,to ensure the generated diffuse images are less affected by visual artifacts and information distortions.A bifurcated feature selection module is designed to remove the specular highlight features,thereby enhancing the detection capability of the *** experiments on two types of challenging datasets demonstrate that our method outperforms state-of-the-art approaches for specular highlight detection and *** effectiveness of the proposed bifurcated feature selection module and the overall network is also verified.

大豆及大豆食品关乎国家的粮食安全,关乎大众的营养与健康,理顺和调控好大豆原料生产、食品加工利用和食品制造现代化之间的发展关系对建设中国特色的现代化强国十分重要。我国是重要的大豆生产国,总产量一直位居世界第四,每年有85%以上国产大豆用于食品加工,但是,目前我国大豆食品产业的发展在产业链、供应链和价值链构建方面还面临诸多问题。在原料利用方面,尽管国产大豆在需求量上保障了大豆食品产业的供给,但品质难以达到专用大豆原料的要求;大豆的混种、混收、混用仍是让大豆食品加工企业感到困惑的难题;国产食品专用大豆原料要在未来保持竞争地位,就要在品种选育、种植管理、产销品质控制方面有明确的定位;需建立统一协调的生产、加工、销售制度体系;完善我国大豆原料标准体系以及大豆品种名和加工产品商品名统一的原料标示推广系统。在产业加工方面,大豆食品加工现代化工作在近些年取得了很大的进步,但在传统工艺深度挖掘和新技术、新产品开发方面不足,针对增强营养健康和不同使用功能性诉求的产品市场细分尚需加强。今后,我国的大豆食品加工新技术、新产品、新装备等开发一定要走与数字化技术相结合的道路,不断地提升大豆食品加工的数字化、智能化水平,实现原料、储运、产品生产、制造和流通整个产业链的绿色制造和现代化。

本文以中共十八届五中全会提出的共享发展理念为指导,以马克思"自由人的联合体"思想和安德森"命运共同体"理论为基础,探讨社会保障制度建设对当代中国国家共同体构建的重要价值。中国现行社会保障制度以单位制为基础,已不能适应当下经济社会的剧烈转型,亦无法应对互联网发展所带来的社会结构的多元化和扁平化变迁。推进社会保障制度顺利转型,不仅关乎国计民生,更关乎中国能否顺利实现经济社会转型,顺利跨越"中等收入陷阱"。结合中国国情,本文提出了符合共享发展和国家共同体理念的社会保障制度改革的具体政策建议。
