An important aspect of collision avoidance and driver assistance systems, as well as autonomous vehicles, is the tracking of vehicle taillights and the detection of alert signals (turns and brakes). The goal of this paper is to present a novel, robust, and efficient algorithm that is capable of detecting and tracking vehicle taillights, recognizing common alert signals using an embedded smart c...

The classic light field and lumigraph are two well-known approaches to image-based rendering, and subsequently many new rendering techniques and representations have been proposed based on them. Nevertheless the main limitation remains that in almost all of them only static scenes are considered. In this contribution we describe a method for calibrating a scene which includes moving or deformin...

This paper proposes a search method for detecting known objects quickly in 3D environments with a pan-tilt-zoom camera. In our previous work, we proposed an algorithm named Active Search that greatly reduces the number of calculations required to obtain a match between a reference object and an input image using color histograms. Here, we describe two improvements we have made to Active Search ...

Augmented reality human machine interface is demonstrated in the cabin of a forest machine outdoors for the first time in real time. In this work, we propose a system setup and a real-time capable algorithm to augment the operator’s visual field with measurements from the forest machine and its environment. In the demonstration, an instrumented forestry crane and a lidar are used to model the p...

This paper presents techniques and animations developed from 1991 to 2000 that use digital photographs of the real world to create 3D models, virtual camera moves, and realistic computer animations. In these projects, images are used to determine the structure, appearance, and lighting conditions of the scenes. Early work in recovering geometry (and generating novel views) from silhouettes and ...

We present a markerless augmented reality system with intuitive positioning and realistic direct lighting of virtual objects. Our approach exploits a two camera system consisting of a TV-camera and a fish-eye camera. The TVcamera captures the video for the augmentation while the fish-eye camera observes the upper hemisphere to track the light sources. Accordingly, direct lighting can be used to...
