Analysis of Ancient Mosaic Images for Dedicated Applications
Lamia Benyoussef, Stéphane Derrode · 2017
This chapter aims to draw an overview of image processing-based methods dedicated to the specificities of mosaic images for applications to restoration and cataloging of ancient mosaics. It gives a description of several projects involving image-processing methods for restoration, preservation, and indexation of ancient mosaics. The chapter presents an effective way to extract tesserae, and exposes two direct applications of this strategy for mosaic image segmentation and coding. It also presents an effective way to retrieve the main guidelines of a mosaic which can be helpful for delimitating semantic objects present in a complex scene. The chapter examines some open issues and suggests future research directions to succeed in providing appropriated tools to museums and experts. Mosaic is a form of art to produce decorative images or patterns out of small components. It requires a great deal of time and labor and it is often very expensive.
