The development of dynamic web has changed the concept for sharing information, allowing quick access to data and enabling the contents update through the active participation of users. Building digital heritage requires substantial resources in materials, expertise, tools and cost. Also there is a necessity of reflection to promote forms of electronic publication adapted to the needs of archaeologists. This contribution describes an approach and it main strategic choices followed in the construction of an open system through Internet to access and share archaeological information concerning to pottery shapes.

A novel shape characterization method, using Mathematical Morphology, is introduced for this purpose. Each profile is represented as a vector, obtained by sampling the so called morphological curves (erosion, dilation, opening and closing), and Euclidean Distance is used as a similarity measure. We show results of our method applied to a profile database of Iberian Pottery from the upper valley of Guadalquivir River (Spain).

We present a new method to characterize and classify wheel-made pottery by its profile , using Mathematical Morphology. Each piece is represented as a vector, obtained by sampling the so called morphological curves (erosion, dilation, opening and closing), and Euclidean Distance is used as a similarity measure. The proposed technique has been studied using a sample of 1133 complete ceramic vessels from the Iberian archaeological sites from the upper valley of Guadalquivir River (Andalusia, Spain), showing that it is compatible with the existing corpus, established by experts.

We use the Douglas-Peucker algorithm to obtain a polyline that preserves the coarse features of the profile shape. A characteristic vector is derived from each polyline, allowing us to compare profiles by measuring the distance between the corresponding vectors. We have tested our technique with a profile database of Iberian pottery vessels from the upper valley of the Guadalquivir River (Spain). Results show that our approach not only achieves better results than most of the state-of-the-art methods used nowadays, but is also more efficient and generates more compact characteristic vectors.
