This paper presents an algorithm for voxel-based reconstruction of objects with general reflectance properties from multiple calibrated views. It is assumed that one or more reference objects with known geometry are imaged under the same lighting and camera conditions as the object being reconstructed. The unknown object is reconstructed using a radiance basis inferred from the reference object...

document imaging, image processing, PDAs, cameras In the past few years we have witnessed the migration of cheap imaging devices into portable and mobile computing appliances such as PDAs and mobile phones. As these devices become ever more powerful in terms of processor speed and memory, new exciting applications and uses are being developed. A particularly useful one is the casual capture of ...

This paper describes a novel system for building seamless texture maps for a surface of arbitrary topology from real images of the object taken with a standard digital camera and uncontrolled lighting. In our application we wish to take a sparse set of real images of a 3D object, and apply the images to an approximate surface model of the object to generate a high quality textured model. In pra...

We present a novel method for the autonomous positioning of surgical lamps in open surgeries. The basic idea is to use an inexpensive depth camera to track all objects and the surgical staff and also generate a dynamic online model of the operation situs. Based on this information, our algorithms continuously compute the optimal positions for all surgical lamps. These positions can then be comm...

The DINION IP starlight 8000 MP offers a new standard in round-the-clock video surveillance. Regardless of lighting conditions, time-of-day or object movement, the camera delivers relevant IP video 24/7. Capturing 16:9 images at 5 megapixel resolution (3K) even under extreme low-light conditions, it gives amazing images in fine detail. The camera produces multi-megapixel full-color video in nea...

We present a practical and inexpensive approach for the acquisition and rendering of static incident light fields. Incident light fields can be used for lighting virtual scenes or to insert virtual objects into real world video footage. The virtual objects are correctly lit and cast shadows in the same way as real objects in the scene. We propose to use an inexpensive planar mirror and a high d...

A wearable low-power hybrid vision-inertial tracker has been demonstrated based on a flexible sensor fusion core architecture, which allows easy reconfiguration by plugging-in different kinds of sensors. A particular prototype implementation consists of one inertial measurement unit and one outward-looking wide-angle Smart Camera, with a built-in DSP to run all required image-processing tasks. ...

Novel photo-realistic texture synthesis is an important task for generating novel scenes, including asset generation 3D simulations. However, to date, these methods predominantly generate textured objects in 2D space. If we rely on object generation, then need make a computationally expensive forward pass each time change the camera viewpoint or lighting. Recent work that can textures requires ...
