abstract: 'In this paper we target the problem of the retrieval of colour patterns over surfaces. We generalize to surface tessellations the well known Local Binary Pattern (LBP) descriptor for images. The key concept of the LBP is to code the variability of the colour values around each pixel. In the case of a surface tessellation we adopt rings around vertices that are obtained with a sphere-mesh intersection driven by the edges of the mesh; for this reason, we name our method edgeLBP. Experimental results are provided to show how this description performs well for pattern retrieval, also when patterns come from degraded and corrupted archaeological fragments.'

Introduction
============

Thanks to advances in the modeling techniques and to the availability of cheaper yet effective 3D acquisition devices, we see a remarkable increase of the amount of 3D data available. Many sensors are able to acquire not only the 3D shape but also its *texture*; this is the case, for instance, of the Microsoft Kinect device. The creation of an increasing number of 3D models has opened new opportunities
