Panoramic Depth Imaging: Single Standard Camera Approach [PDF]

open access: yes, 2001
In this paper we present a panoramic depth imaging system. The system is mosaic-based which means that we use a single rotating camera and assemble the captured images in a mosaic. Due to a setoff of the camera’s optical center from the rotational center

Matterport3D: Learning from RGB-D Data in Indoor Environments

open access: yes, 2017
Access to large, diverse RGB-D datasets is critical for training RGB-D scene understanding algorithms. However, existing datasets still cover only a limited number of views or a restricted scale of spaces.

Categorization of indoor places by combining local binary pattern histograms of range and reflectance data from laser range finders [PDF]

open access: yes, 2013
This paper presents an approach to categorize typical places in indoor environments using 3D scans provided by a laser range finder. Examples of such places are offices, laboratories, or kitchens.

Face tracking using a hyperbolic catadioptric omnidirectional system [PDF]

open access: yes, 2009
In the first part of this paper, we present a brief review on catadioptric omnidirectional systems. The special case of the hyperbolic omnidirectional system is analysed in depth.

EgoSampling: Wide View Hyperlapse from Egocentric Videos

open access: yes, 2017
The possibility of sharing one's point of view makes use of wearable cameras compelling. These videos are often long, boring and coupled with extreme shake, as the camera is worn on a moving person. Fast forwarding (i.e.

Panoramic Views of the Cygnus Loop [PDF]

open access: yes, 1998
We present a complete atlas of the Cygnus Loop supernova remnant in the light of [O III] (5007), H alpha, and [S II] (6717, 6731). Despite its shell-like appearance, the Cygnus Loop is not a current example of a Sedov-Taylor blast wave.

Reactive direction control for a mobile robot: A locust-like control of escape direction emerges when a bilateral pair of model locust visual neurons are integrated [PDF]

open access: yes, 2010
Locusts possess a bilateral pair of uniquely identifiable visual neurons that respond vigorously to the image of an approaching object. These neurons are called the lobula giant movement detectors (LGMDs). The locust LGMDs have been extensively studied
