基于统计模型的书法创作模拟

人们对抽象思维与形象思维的认识极不平衡,对形象思维过程的研究尚属阙如.书法创作是典型的形象思维过程.文中给出基于带参数的统计模型(X=M(b))的书法笔划变形方法,通过调节参数可生成新风格的笔划.其过程包括从笔划轮廓获得训练点集、利用广义Procrustes分析法对齐、由主成分分析法得到特征等,并以隶书中典型的"一"划为例,讨论模拟创作结果.要实现人工智能,形象思维的模拟、模式和模型是逐步要考虑的问题.目前的工作只是第一步.

Value creation in software service platforms

In order to benefit from operating an IT service platform (e.g., SaaS platform), platform providers need to find a way to keep their existing users and application services active sources of value. However, the understanding of how to achieve that is limited due to the newness of this kind of business. This paper investigates whether all stakeholders of the platform ecosystem can generate sufficient value when participating in the platform. As stakeholders, we consider application service users, service developers, and service platform providers. We also analyse the interrelationship between these stakeholders. The analysis outcome is a value creation model that allows the calculation of the stakeholders’ values. The model also helps inferring the relative impact of different factors on the evolution of values of the software service platform stakeholders. Our simulation results confirm that all stakeholders of a service platform mainly benefit from a growing installed base of application users. However, in a mature market, a large service variety mainly benefits the service platform provider, while the other stakeholders obtain a reduced increase in their benefits. In particular, the utility growth of application users becomes constrained as the benefit from new connections with other users decreases and the number of new services used decreases. Similarly, the revenue of service developer decreases, making service development less profitable. Therefore, we can state that not only a large fraction of the value creation goes to the platform provider but also that the software service ecosystem can collapse, if no mutually beneficial pricing of services is implemented.     

关于艺术设计专业毕业创作的几点思考

在目前就业压力大增的情况下,许多艺术设计专业的毕业生把毕业创作的时间全部用于找工作或考研,不重视甚至完全忽视毕业创作。教师应该让这些学生正确认识到毕业创作的重要性,学会合理安排时间,让毕业创作成为他们今后人生的一个新起点。     

基于区块链的建筑信息模型图纸多人协同创作系统

建筑信息模型(BIM)图纸多人协同创作在大型建筑项目中很重要,而现有的基于Revit等建模软件或云服务的BIM图纸多人协同创作方法存在BIM图纸版本混乱、不易溯源以及数据安全风险等问题.针对这些问题,设计了一种基于区块链的BIM图纸多人协同创作系统.该系统采用链上链下协同的存储方式,使用区块链和数据库分别存储BIM图纸...     

国画“留白”在包装设计中的运用

"留白"是中国绘画艺术中的一个非常重要的术语,被广泛的应用在中国传统的书画创作中。"留白"是艺术达成审美交流的中介机制,它深刻的展开了艺术的创作过程与接受过程的视野融合,具有极高的设计与文化价值,是现代包装设计师在设计思维和设计手法上可供学习和借鉴的宝库。本文从国画"留白"艺术的构成方法、风格、布置等角度进行了论述。总结了其设计特点和艺术手段,以通过对国画"留白"艺术设计理念的探讨对现代包装设计给予启发与引导。     

Understanding value creation in closed loop supply chains – Past findings and future directions

The topic of value creation through the recovery of returned products in closed loop supply chains is scattered across various bodies of literature. We undertake a systematic literature review of 144 articles in relevant green, reverse and closed loop supply chain literature to synchronize existing knowledge on value creation. Value manifestations of four types of value, namely economic, environmental, information and customer value, are identified. Value adding concepts from the forward- and reverse supply chain may leverage the process of value creation. They are classified into six subclasses, namely partnerships and collaboration, product design characteristics, service concepts, IT solutions, supply chain processes and organizational characteristics. We present a conceptual framework on a strategic level. In this way companies can create competitive advantages by closing the loop. The results of the literature analysis suggest avenues for future research on the operational and strategic level.     

浅析插画艺术中的潜意识表现

插画创作需要创新,创新来自灵感,灵感需要突发,需要潜意识的表现,超常规非现实、从潜意识的深渊流溢出的灵感在插画艺术中的运用赋予了受众丰富的想象空间。插画艺术的创作应该用形象语言说话,将现实的插画艺术通过潜意识的表现,丰富思维转化成视觉元素。本文在于正确认识和激发潜意识,在创作时不断地用充满希望与期待的画面与潜意识交谈,让我们的插画艺术更具识别和视觉冲击力。     

基于图像化几何的三维模型彩绘

基于纹理映射的彩绘系统通常受到从三维模型空间到二维纹理空间参数化的限制.如果一个模型具有复杂的拓扑结构或高度复杂的表面细节,寻找一个好的参数化方法通常是非常困难的,即使可以实现,通常也不能自动完成,需要用户手工交互进行.针对这种问题,提出了一种用于在三维模型表面直接进行彩绘的数据表示方法和一个原型系统,通过在三维模型中的每一个三角形上生成带有颜色信息的几何点,该系统可以支持许多与二维图像编辑类似的操作.其中一个关键的内容是提出了一种包含几何、拓扑和色彩信息在内的自适应的数据表示方法.这种方法被称为图像化的几何,它允许用户将每一个三角形视为一个三角形图像,并可以在不需要任何参数化的前提下在三维模型表面进行彩绘.系统的输入为一个常见的三角形网格模型,通过系统处理后变成一个在三角形上分布着带有颜色信息的几何点的三维表面.因为创建过程是自适应的,因此只有那些需要进行绘画纹理的三角形才需要创建几何点,这样可以节省存储消耗.将这种数据表示用于三维模型彩绘可以很好地处理具有复杂拓扑结构的模型.     

Collecting and evaluating the CUNY ASL corpus for research on American Sign Language animation

While there is great potential for sign language animation generation software to improve the accessibility of information for deaf individuals with low written-language literacy, the understandability of current sign language animation systems is limited. Data-driven methodologies using annotated sign language corpora encoding detailed human movement have enabled some researchers to address several key linguistic challenges in ASL generation. This article motivates and describes our current research on collecting a motion-capture corpus of American Sign Language (ASL). As an evaluation of our motion-capture configuration, calibration, and recording protocol, we have conducted several rounds of evaluation studies with native ASL signers, and we have made use of our collected data to synthesize novel animations of ASL, which have also been evaluated in experimental studies with native signers.
