The paper describes calibration and epipolar rectification for stereo with fish-eye optics. While stereo processing of classical cameras is state of the art for many applications, stereo with fish-eye cameras have been much less discussed in literature. This paper discusses the geometric calibration and the epipolar rectification as prerequisite for stereo processing with fish-eyes. First, it s...

Catadioptric Omni-Directional Stereo Vision (ODSV) technology is the combination of omni-directional imaging and stereo vision, which has wide application potentials on robot vision and large-scale video surveillance [1-4]. Fig.1 gives the framework of ODSV technology, which includes four major parts: the design of omni-directional stereo vision imaging system, unwarping of omni-directional ste...

In this paper, CMU video-rate stereo machine based on multi-baseline method is introduced. It is a dedicated hardware for very fast range measurement. A calibration method suitable for multi-baseline stereo is also shown. Finally the performance is demonstrated in an indoor scene. Direct motivation of the development of stereo machine is to use it as a range sensor in autonomous navigation vehi...

This paper shows how stereo and Time-of-Flight (ToF) images can be combined to estimate dense depth maps in order to automate plant phenotyping. We focus on some challenging plant images captured in a glasshouse environment, and show that even the state-of-the-art stereo methods produce unsatisfactory results. By developing a geometric approach which transforms depth information in a ToF image ...

Many fielded mobile robot systems have demonstrated the importance of directly estimating the 3D shape of objects in the robot’s vicinity. The most mature solutions available today use active laser scanning or stereo camera pairs, but both approaches require specialized and expensive sensors. In prior publications, we have demonstrated the generation of stereo images from a single very low-cost...

the desire and drive for excellence in any endeavor in life requires an effort from the individual; in addition it requires a constellation of features around such individuals that help them to become successful. for surgeons, it is the operating room staff, the administrative and medical assistants and our residents and fellows. however, perhaps the most important contribution to a physician’s...

This paper introduces into seven real-world road driving stereo sequences (provided by Daimler AG, Germany; now freely available for academic research); it also informs about their use for performance evaluation in some experiments using common stereo and motion analysis algorithms. Often, such algorithms are tested on a few frames only, or on synthetic sequences, but not on long real-world seq...

Binocular deficits are relatively common within a typical sample of observers. This has implications for research on binocular vision, as a variety of stereo deficits can affect performance. Despite this, there is no agreed standard for testing stereo capabilities in observers and many studies do not report visual abilities at all. Within the stereo literature, failure to report screening and s...

A review of the facts about human stereo vision leads to the conclusion that the human stereo processing mechanism is very flexible in the presence of other depth cues. Stereopsis seems to provide only local additional depth information, rather than defining the overall 3D geometry of a perceived scene. This paper reports on an experimental approach to adjusting stereo parameters automatically ...

Most of the research in music information retrieval (MIR) is concentrating only on monophonic source signals. The stereo information has been ignored largely in the research many years. However, commercially available music recordings typically consist of a two-track stereo mix. The type of mixing process used in the recordings can be roughly categorizes into live recordings and studio recordings.
