Abstract—In this paper, a system is proposed to automatically generate 3D model of fountains from a single image. Although a single image is usually not sufficient for determining the 3D structure in an image; here we utilize our prior knowledge of general characteristic structures of fountains over the history such as the similarity of their top parts and their symmetrical shape. Firstly, object is detected and labelled on image using Convolutional Neural Networks (CNNs). Then, the object is segmented from background with Graph Cut technique and the contour of the object is used to estimate the shape of 3D model. Finally, 3D model of the fountain is completed by applying the texture acquired from the input image.

I. Introduction

Architectural heritage is one of the most important components of cultural heritage. Turkey is a country with a wealth and diversity at a universal level in terms of cultural heritage and ablution fountains (şadırvan in Turkish) form an important class of architectural heritage and they have an important place in Turkish-Islamic architecture. Through the history, various...
