Systems and methods for computing and displaying navigation indicators based on historic and real-time vessel data

Julien Pilet, Jonas Olof Martin Östlund

System and methods for computing true wind and true current are described. True wind estimation occurs through automatic calibration of data obtained from data acquisition devices (102, 114, 116, 118, 120). Real-time boat performance information is generat ...

Fast Non-Rigid Surface Detection, Registration and Realistic Augmentation

Pascal Fua, Vincent Lepetit, Julien Pilet

We present a real-time method for detecting deformable surfaces, with no need whatsoever for a priori pose knowledge. Our method starts from a set of wide baseline point matches between an undeformed image of the object and the image in which it is to be d ...

Making Background Subtraction Robust to Sudden Illumination Changes

Pascal Fua, Christoph Strecha, Julien Pilet

Modern background subtraction techniques can handle gradual illumination changes but can easily be confused by rapid ones. We propose a technique that overcomes this limitation by relying on a statistical model, not of the pixel intensities, but of the ill ...

Retexturing in the Presence of Complex Illumination and Occlusions

Pascal Fua, Vincent Lepetit, Julien Pilet

We present a non-rigid registration technique that achieves spatial, photometric, and visibility accuracy. It lets us photo-realistically augment 3D deformable surfaces under complex illumination conditions and in spite of severe occlusions. There are many ...

Surface Deformation Models for Non-Rigid 3--D Shape Recovery

Pascal Fua, Mathieu Salzmann, Slobodan Ilic, Julien Pilet

3--D detection and shape recovery of a non-rigid surface from video sequences require deformation models to effectively take advantage of potentially noisy image data. Here we introduce an approach to creating such models for deformable 3--D surfaces. We e ...

An all-in-one solution to geometric and photometric calibration

Pascal Fua, Vincent Lepetit, Julien Pilet, Pascal Lagger, Andreas Geiger

We propose a fully automated approach to calibrating multiple cameras whose fields of view may not all overlap. Our technique only requires waving an arbitrary textured planar pattern in front of the cameras, which is the only manual intervention that is r ...

Augmenting Deformable Objects in Real-Time

Pascal Fua, Vincent Lepetit, Julien Pilet

We present a real-time system that can draw virtual patterns or images on deforming real objects by estimating both the deformations and the shading parameters. We show that this is what is required to render the virtual elements so that they blend convinc ...
