Remote sensing/Road design and Applications using Technology/Transport engineering on Earth and Space), ABSTRACT:This paper has several aims: a) the presentation of a critical analysis of the terms "smart sustainable cities" and "smart sustainable islands" b) the presentation of a number of principles towards to the development methodological framework of concepts and actions, in a form of a manual and actions guide, for the smartification and sustainability of islands. This kind of master plan is divided in thematic sectors (key factors) which concern the insular municipalities c) the creation of an island's smartification and sustainability index d) the first steps towards the creation of a portal for the presentation of our smartification actions manual, together with relative resources, smart applications examples, and, in the near future the first results of our index application in a number of Greek islands and e) the presentation of some proposals of possible actions towards their sustainable development and smartification for the municipalities -islands of Paros and Antiparos in Greece, as case studies.

This paper proposes a performance evaluation method for text detection in color images. The method, contrary to previous approaches, is not based on the inexplicitly defined text bounding boxes for the evaluation of the text detection result but considers only the text pixels detected by binarizing the image and applying a color inversion if needed. Moreover, in order to gain independence from the chosen binarization algorithm, the method uses the skeleton of the binarized image. The results produced by the proposed evaluation protocol proved to be quite representative and reasonable compared to the corresponding optical result.
