We suggest that a battery of handwriting indices be used to characterize handwriting.
Application of the suggested methods may well make the difference between a nonconclusive handwriting examination and a full analysis of the questioned handwriting.
These results demonstrate the efficiency of Fourier transform infrared spectroscopy for classification.
The findings support a hierarchical model of handwriting.

What is the use of infrared spectroscopy?5 answersInfrared spectroscopy is a technique used to identify and determine components in various organic or inorganic compounds. It is commonly used in qualitative and quantitative analyses, including the estimation of compounds through measuring the transmitted or absorption intensity of active groups. In the field of heterogeneous catalysis research and development, infrared spectroscopy is used for structural characterization, such as identifying surface metal-oxygen bonds and surface acid sites. Additionally, infrared spectroscopy can be used to automatically identify functional groups in molecules without the need for database searching or peak matching methods. The technique is also powerful for structural analysis, as it allows for the identification of functional groups in solids, liquids, or gases by analyzing obtained spectra. In the analysis of food toxins, infrared spectroscopy is a non-destructive and rapid method for the detection and characterization of contaminants in high throughput.
How IR spectroscopy can be helpful in analysis of textile and art?5 answersIR spectroscopy is helpful in the analysis of textiles and art. In the case of textiles, IR spectroscopy can be used to identify natural fibers, distinguish between isomers and conformers of synthetic fibers, and analyze modified and functionalized textile materials. It can also be used in mixture ratio analysis of textile products, providing a non-destructive and quick method for manufacturers. In the field of art, IR spectroscopy, specifically FT-IR and FT-Raman, can be used to characterize genuine and fake artifacts, provide information for strategic restoration, assess the effects of environmental degradation on artwork, and identify pigments. Additionally, IR spectroscopy combined with multivariate statistical methods and machine learning classification models can be used to classify synthetic textile fibers, aiding in the investigation of crime scenes.
