"Multivariate analysisIn order to increase the information content in a FTIR image, Principal Component Image Analysis (PCIA) was developed for FTIR image analysis. It could be shown that PCA analysis is able to extract characteristic sets of IR absorption bands which correlate with the sample's components and greatly improve the selection process of wavenumbers used for the visualization of the different components. During 1998 these algorithms and the corresponding user interfaces have been optimized. It is now routinely used as an analytical tool in the examination of the FTIR paint-cross section data, described in that project."

Description: “Paintings are perceived by the human eye as a result of the reflected light in the visible region of the electromagnetic spectrum. The returned spectrum strongly depends on the absorbance characteristics of the surface of the painting. The ratio between various absorption's and reflections at different wavelengths determines the contrast and brightness of paintings. In other parts of the electromagnetic spectrum it is possible to observe different features of a painted work of art which can elucidate the creative process, chemical features of the materials used and the state of preservation of a painting. In this project we examine paintings and paint samples (embedded paint cross-sections) with a number of spectroscopic techniques as described in the description of the analytical instrumentation developments. Infrared reflectography is used to study the underdrawings of paintings, FTIR-microscopic imaging is used to study embedded paint cross-sections and FTIR-emission spectroscopy will be used to study the chemical nature of the surface of the painting. As a result of the evaluation procedure the project on spectroscopic imaging of entire paintings in the UV and VIS spectral region has been terminated.”

"Outline of Analytical Methods used for Paint Analysis.
Paintings can be analyzed for their molecular content by using a variety of different instrumental methods of analysis [13]. The principal methods applied to paintings are chromatographic and spectrometric. Chromatographic analysis of paintings can involve the use of thin-layer chromatography (TLC), gas chromatography (GC) and liquid chromatography (LC). TLC is typically only used to obtain rapid information about a particular class of analyte being present in the painting. The lack of resolving power forces the use of GC and LC methods for separation and quantitative analysis"

Subject : art paintings/ content analysis/ chemical analysis/ art conservation
Description : « This manuscript is envisioned as a “living” progress report for my attempt at Rensselaer Polytechnic Institute to use art conservation methods as a means to help better teach analytical chemistry. The intent is to update this manuscript and web site as a means to provide additional information about what works and what does not work with respect to project based learning with this approach in the Instrumental Methods of Analysis laboratory. This report gives a brief introduction to the chemistry of paintings. Additionally, the different instrumental approaches commonly used to identify various chemical components of paintings are described. Next, this report describes a recent effort at Rensselaer Polytechnic Institute to bring project-based learning to the upper-level instrumental analysis laboratory. The molecular analysis of a painting (The Buffalo Room, by Robert Chanler) that needed to be conserved was used as the basis for this project. The unique chemical qualities of paintings that make this type of chemical analysis highly challenging are described. Finally, lessons learned from our first attempt to bring forth this type of learning to our students are described. »

"2.1 Image-Based Modelling (IBM)
Image data are probably the most complete source for digital documentation and 3D modelling. Indeed, geometry and texture information can be derived at the same time, using cheap sensors and fast procedures. Generally the image measurement phase is regarded as the most tedious part leading non-expert to consider this modelling approach as inappropriate, time consuming and, with the advent of range sensors, as out-ofdate.
Between IBM methods, photogrammetry is a highly accurate and flexible approach, suited for different scales and used to derive metric and reliable information of a scene from a
set of images [Remondino and El-Hakim, 2006]. Images acquired in the visible domain are generally employed, even if IR or UV data could also be employed. Old images, stored in
databases or archives, may be also used to document lost objects [Grün et al., 2004]."

Description : "The digital documentation and 3D modelling of Cultural Heritage monument and sites is receiving great attention in the last years. There is a large variety of technologies for 3D surveying purposes and generally a technique is chosen according to the project requirements, operator experience, budget and location constraints. Digital images and range sensors (laser scanner or stripe projection systems) are generally the most used technologies used to virtually reconstruct the whole geometry of the studied heritage. The combination of the two recording methods has demonstrated to be an efficient way of 3D modeling as no technique by itself is able to provide accurate 3D results in all the applications and in short time. Other data are becoming nowadays pretty common and important for a more deep documentation and investigation of heritages, i.e. image data coming from the light
spectrum outside the visible range. In this work, we present how we derive geometric 3D models of heritage structures by means of close-range photogrammetry or range sensors while extra information acquired with infrared cameras are used for texture mapping purposes and other studies. Data obtained from all those instruments are registered and fused together for documentation reasons, historical studies, restoration plans and visualization purposes."
