A hierarchical two-dimensional structural iamge segmentation algorithm based on a contour tree description is presented. This format is compared with more traditional facsimile coding standards (T.4, T.6 and T.82) (as well as other common compression standards) on the standard ITU test set of facsimile images. A detailed study of the coding complexity and choices required to design a general contour coding strategy is carried out. A final choice of parameters is presented and compared against previous work on gray-scale imagery.

The subject of facsimiles has rarely been explored in Polish bibliology. That is why the present study is an attempt to systematise the knowledge of the subject on the basis of bibliological and scholarly sources, both Polish and foreign. Facsimiles are made to represent the most important features of documents, including the faithfulness in the reproduction of the original, content added during facsimile edition (back matter, commentary) as well as formal and editorial features. The very process of producing a facsimile consists in advanced scanning of the original document, precise printing guaranteeing faithful reproduction of colours, manual treatment (e.g. cutting of holes, gilding etc.) and binding. All these elements are to make the facsimile similar to the original as much as possible. Facsimiles serve as substitutes of original documents, making it possible to disseminate and protect the originals, and use them in research or popularising activities. Given the aesthetic and material value, they may also become collector’s items or investments for potential users. Today facsimiles are undergoing transformations in the context of their roles and functions.
The text offers enlightening reflections on issues concerning reproductions of works of art, the status of an original and a copy, the problem of conservation, and the role of digital photography. Latour and Lowe raise the contentious issue of how good and bad reproductions can affect the original, participate in what they call “the migration of the aura”. This is primarily a case study of a production, presentation, reception and the meaning of a facsimile of a Veronese work, Nozze di Cana at its original location, San Giorgio in Venice. The second part of the text (the appendix) is a meticulous, technical description of the stages of production of the picture by Lowe.
