不同品种大豆加工石膏豆腐的适宜性研究

试验选取了2013年五河野生大豆、2014年五河野生大豆、中黄13、小金黄、东农53、黑豆一号等6种大豆,通过传统的石膏豆腐加工工艺,对6种豆子进行了加工。通过对成品豆腐产率、感官评分、质构分析及营养素的测定等多个方面的比较,研究了不同品种豆腐品质的差异。结果表明,相对更加适合加工石膏豆腐的大豆品种是中黄13、小金黄及黑豆一号。

肌理——油画之美——漫谈油画作品肌理的重要性

油画作为思维和技术的结晶,具备实体性,其画面的表面结构—肌理,必然成为油画的绘画语言。一切优秀的作品都是物质与精神的完美结合,油画肌理便是物质与精神碰撞的产物,是画家内心情感的外化,是画家通过物质实现精神世界轨迹的恒久驻留。     

Mean shift texture surface detection based on WT and COM feature image selection

INTRODUCTION Visual inspection plays a vital role in assuring the quality of industrial products. Texture surface detection aims at detecting defects such as cracks, stains, broken points, etc. on texture surfaces. Due to the repetitive changes of texture gray values and structures, traditional detection methods based on intensity or edge detection are invalid, which makes texture surface detection one of the most intriguing problems during the past decades. Generally, most of previous a…     

Re-C共渗渗层组织研究

研究了稀土元素庄渗碳过程中对渗层组织的影响。结果表明：稀土能使渗碳过程加快、渗层加厚、时间缩短;稀土对碳钢的渗层组织无明显的细化;稀土能使合金钢表层碳化物颗粒细化,均匀弥散分布,碳化物层加厚。     

基于模拟退火算法的Tile集生成优化

纹理合成技术是计算机图形学、计算机视觉和图像处理领域的研究热点之一,其中因Wang-Tile纹理合成方法可以实时地生成任意大小的纹理而受到人们的关注。Tile集的生成是Wang-Tile纹理合成方法的一个重要方面,但由于其中样本纹理选择的随意性使得合成纹理出现明显的菱形接缝。采用模拟退火算法来实现样本纹理选择过程的全局优化,提高了Tile集的质量,得到了理想的合成结果,对此进行了论述。

论肌理在装饰设计中的应用

肌理作为一种具有特质美感的艺术形式,已被广泛应用于装饰设计领域,其独特的艺术魅力越来越受到人们的重视和青睐,并成为设计者们创作表达自我情感的一种重要方式。肌理的存在依托于材料,从视觉和触觉两方面带给人们艺术享受,不同的肌理形式传递着不同的审美情感和心理感知。本文主旨意在探索感知装饰材料的肌理魅力,及其在装饰设计中恰当、灵活的运用,以展现肌理的内质美。     

Using 3D digital models for the virtual restoration of polychrome in interesting cultural sites

In most cases, the polychrome paintings that decorated heritage buildings no longer exist or are reduced to mere remnants. These facts decontextualize the sites in their historical and artistic evolution, distort the intention under which they were conceived, and hamper their accomplishment. Current recovery methods are restricted to the stabilization of the remains in their present status, requiring a lot of completely manual work that is expensive and almost unrelated to the use of new technologies. Three-dimensional digitalization and modelling is proved to be the basis for the virtual recovery of paintings in a significant edifice. To do so, an innovative methodology is presented that allows the 3D geometric information of a site (captured using a laser scanner) to be combined with specially designed 2D artistic images. The resulting 3D digital models can then be focused, with high efficiency projectors, on the equivalent area of the original site, and also used as raw material to compose a video-projection without perspective effects to emulate, with due rigour, the primitive appearance, its evolution along time, the effects of the deterioration, or other interesting aspects. The results obtained at Sta. María de Mave (Palencia, Spain) are presented, supporting the potential of this new methodology not only as a scientific way to discuss possible restoration hypotheses with experts or as a didactic tool for narrating the historical evolution of a monument, but also as a spectacular show for tourists.
