Coffee growers feel the heat
Coffee has for several decades now been a flagship product of the efforts to make trade with the developing world fair and to ensure that smallholder producers in tropical countries can make a reasonable living from the produce they export to the more affluent parts of the world. Now coffee is also set to become a prime example of how climate change disrupts agricultural production and endanger...
متن کاملInside the Parchment
Even though parchment has been applied as library and archive substrate for centuries, this material’s structure and degradation patterns are less explored than paper’s ones. In this preliminary work vibrational studies highlighting distinction between parchment components are presented. Advances in conservation methods can in fact be achieved by an improved knowledge of the microscopic and spe...
متن کاملAutoxidation of Lipids in Parchment
Historic parchment is a macromolecular material, which is complex due to its natural origin, inhomogeneity of the skin structure, unknown environmental history and potential localised degradation. Most research into its stability has so far focussed on thermal and structural methods of analyses. Using gas-chromatographic analysis of the atmosphere surrounding parchment during oxidation, we prov...
متن کاملMultispectral Imaging of Degraded Parchment
Multispectral imaging was employed to collect data on the degradation of an 18 century parchment by a series of physical and chemical treatments. Each sample was photographed before and after treatment by a monochrome digital camera with 21 narrow-band filters, with the objective of assessing algorithms for recovery of text from the images. A template-matching technique was used to detect the c...
متن کاملSAMKO: SEGMENTATION OF PARCHMENT SCROLLS FOR VIRTUAL UNROLLING 1 Segmentation of Parchment Scrolls for Virtual Unrolling
In this paper we introduce a framework for the segmentation of scanned scrolled parchments, based on a novel graph cut based approach with an additional shape prior, in combination with anisotropic diffusion and geometry-constrained postprocessing. This problem has not been investigated by the computer vision community properly yet due to the parchment scanning technology novelty, and is extrem...
