The two volume set LNCS 9256 and 9257 constitutes the refereed proceedings of the 16th International Conference on Computer Analysis of Images and Patterns, CAIP 2015, held in Valletta, Malta, in September 2015. The 138 papers presented were carefully reviewed and selected from numerous submissions. CAIP 2015 is the sixteenth in the CAIP series of biennial international conferences devoted to all aspects of computer vision, image analysis and processing, pattern recognition, and related fields.

Stones can serve an infinite array of functions both when they are worked and when they are left in a 'raw' state. Depending on their function, stones can also be meaningful objects especially when they act as vehicles of ideas or instruments of representation. And it is, therefore, in their functional context, that the meaning of stones can be best grasped. The stones dealt with in this study are non-figural (or aniconic) or, sometimes, semi-figural. They come from ritual contexts and, as such, act as a material representation of divine presence in their role as betyls. But it is not mainly the representational aspect of these stones that this study seeks to highlight. As material representations of divine presence that are also worshipped, these particular stones form part of a phenomenon that seems to know no geographical or temporal boundaries. They are of a universal character. It is this universal character of theirs that seems to qualify these stones as elements forming part of the phenomenon of continuity: continuity across different cultures and in different places along several centuries. It is this phenomenon which this study seeks to highlight through a study of these stones. The Maltese islands are presented as a case study to demonstrate the phenomenon of continuity through a study of these stones. Worship of stones in representation of divine presence is found on the Maltese islands since prehistoric times. But the practice survived several centuries under different cultures represented by unknown communities during the islands' prehistory and the Phoenicians / Carthaginians and the Romans in early historic times.

The secluded sanctuary on the coastal promontory of Ras il-Wardija on the central Mediterranean island of Gozo (near Malta) constitutes another landmark on the religious map of the ancient Mediterranean. Ritual activity at the sanctuary seems to be evidenced from around the 3rd century BC to the 2nd century AD and, possibly, even as late as the 4th century AD. This ritual activity was focused in a small built temple and in a rock-cut cave that seems to have incorporated a built extension in a later stage. But the practised cult or cults were aniconic and remained so largely throughout. This may explain why the sanctuary's excavators did not report any findings of statuettes or any figural images. Contemporaneously, figural images were also venerated on other sites showing that, for a long while, iconism and aniconism co-existed on the Maltese islands. There might have been more than one deity venerated in this sanctuary. Dionysos could have been one of them. But whoever they were, they are likely to have been somehow connected with the sea and / or with a maritime community or communities as the sanctuary itself evidently was.
