PROJECT ABSTRACT "Counting Van Gogh and Vermeer" Automated thread counting algorithms, in development since 2007 by Professors Rick Johnson (Cornell University) and Don Johnson (Rice University), are poised for a profound impact on the practice of technical art history. This work is a pioneering effort in the emerging application of signal and image processing to the analysis of paintings. The approach is based on the utilization of spectral analysis of x-rays of paintings. X-rays can display the periodic intensity pattern due to the greater thickness of the lead white ground between the canvas threads. With the addition of innovative application-specific signal processing, local peaks in the spectrum of the x-ray data can reveal the numbers of threads per centimeter, i.e. a thread count, separately for (nearly) vertically and (nearly) horizontally oriented threads. Such thread counts have been used previously, but their manual acquisition proved too costly to be done thoroughly. The introduction of the capability to assemble previously unthinkable thread density and angle pattern maps of high detail across the entire surface of a painting leads to correlation-based identification of canvases sharing the same pattern in thread density variations. Such weave maps and matches can now be assembled across all of the paintings on canvas of a single artist or school, thereby significantly extending the art historian's capabilities in, for example, dating and attribution. The scale, breadth, and depth of such thread-counting projects represent a bold leap in the capabilities of technical art history. This grant supports the analysis phase of the projects of such grand scope: the thread counting and subsequent weave matching among (i) all of the paintings by Vincent van Gogh (for which data can be obtained by the end of 2010) and (ii) all of the paintings by the Delft School during the career of Johannes Vermeer (for which data can be obtained by the end of 2010). This grant places Professors Rick and Don Johnson in the center of the data fusion, data analysis and database creation activities that are scheduled to occur in Amsterdam during the spring of 2011. The archives being established of thread count reports, including weave density maps providing fingerprints for weave matching and angle maps for characterizing cusping, form a groundbreaking resource at a time when museums are just beginning to address the technological and cultural barriers to technical data sharing among museums and collaborating researchers outside the museum. This project is part of a long-term effort that aims to expand the utility of thread counting from x-rays to all suitable oil paintings on canvas, and to photos of unlined backs of old master paintings and of the raw canvas, for example, of the modern colorfield painters and of densely-woven, multi-pattern fabrics prominent in the design and decorative arts.

项目摘要“计数van Gogh and vermeer”自动化线程计数算法，自2007年以来，由里克·约翰逊（Rick Johnson）教授（康奈尔大学）和唐·约翰逊（Don Johnson）（莱斯大学）（Rice University）开发，对技术艺术历史实践产生深远影响。这项工作是在新兴的信号和图像处理对绘画分析的新兴应用中的开创性工作。该方法基于对X射线X射线的频谱分析的利用。 X射线可以显示由于画布螺纹之间的铅白色地面厚度更大，因此可以显示周期强度的模式。通过添加创新的应用规格＆＃64257; c信号处理，X射线数据频谱中的局部峰可以揭示每厘米的螺纹数量，即螺纹计数，分别为（几乎）垂直）和（几乎）水平方向的线。以前已经使用了此类线程计数，但是它们的手动采集事实证明太昂贵了，无法彻底完成。 The introduction of the capability to assemble previously unthinkable thread density and angle pattern maps of high detail across the entire surface of a painting leads to correlation-based identification of canvases sharing the same pattern in thread density variations.现在可以在单个艺术家或学校的画布上组装这样的编织地图和比赛，从而大大扩展了艺术史学家的能力，例如约会和归属。此类线程计算项目的规模，广度和深度代表了技术艺术史的能力大胆飞跃。这项赠款支持了这种宏伟范围的项目的分析阶段：线程计数和随后的编织匹配（i）Vincent van Gogh的所有绘画（在2010年底可以在2010年底之前获得数据）和（ii）DelfT学校的所有绘画在Johannes Vermeer的职业生涯期间（供Johannes vermeer的职业生涯）（供哪些数据获得2010年的最终）。该赠款将教授里克和唐·约翰逊教授置于数据融合，数据分析和数据库创建活动的中心，这些活动计划在2011年春季在阿姆斯特丹进行。建立了线程计数报告的档案，包括编织密度图，包括编织指纹的指纹，以构成构建范围的范围，以构成构成杂物的范围，以构成技术的范围，从而启动了构图，从而启动了构图，从而开始了界限，从而开始了界限，并在范围内开发了博物馆的界限博物馆之间的数据共享和博物馆外的研究人员合作。该项目是一项长期努力的一部分，旨在将线程计数的实用性从X射线扩展到画布上的所有合适的油画，以及旧的大师绘画和原始画布的无衬里的照片，例如现代色彩界画家，以及密集的，密集的，多型的，多型的面料，在设计和装饰艺术品中突出。
