We present a completely automatic and scalable framework to perform query-by-example word-spotting on medieval manuscripts. Our system does not require any human intervention to produce a large amount of annotated training ...

Given a color image of a medieval manuscript page, we propose a simple, yet efficient algorithm for automatically estimating the number of its color-based pixel groups, K. We formulate this estimation as a minimization ...

Historical and artistic handwritten books are valuable cultural heritage (CH) items, as they provide information about tangible and intangible cultural aspects from the past. Massive digitization projects have made these ...

We present a state-of-the-art system for obtaining and exploring large scale three-dimensional models of urban landscapes. A multimodal approach to reconstruction fuses cadastral information, laser range data, and oblique ...

New embedded CPUs that sport powerful graphics chipsets have the potential to make complex 3D applications feasible on mobile devices. In this paper, we present a scalable architecture and its implementation for mobile ...

We present a simple, fast and robust technique for semi-automatic 2D-3D registration capable to align a large set of unordered images to a massive point cloud with minimal human effort. Our method converts the hard to solve ...

Nowadays, 3D acquisition devices allow us to capture the geometry of huge Cultural Heritage (CH) sites, historical buildings and urban environments. We present a scalable real-time method to render this kind of models ...

We present a client-server framework for network distribution and real-time point-based rendering of large 3D models on commodity graphics platforms. Model inspection, based on a one-touch interface, is enriched by a ...

We focus on developing a simple and efficient unified level-of-detail structure for networked urban model viewers. At the core of our approach is a revisitation of the BlockMap [CDG*07] data structure, originally introduced ...

We propose to exploit the color capabilities of recent rapid prototyping hardware devices to enhance the visual appearance of reproduced objects. In particular, by carefully pre-computing surface shading, we are able to ...
