Applied Optics, 1994
An infrared panoramic lens system that utilizes two lens groups to project a full 3600 cylindrical field of view onto a two-dimensional annular format is described. Each lens group has its well-defined role. The first group is a lens block that converts a cylindrical field of view into a two-dimensional annular format located within the lens itself ...

Proceedings CVPR IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 1996
This paper is concerned with acquiring panoramic focused images using a small field of view video camera. When scene points are distributed over a range of distances from the sensor, obtaining a focused composite image involves focus computations and mechanically changing some sensor parameters (translation of sensor plane, panning of camera etc ...

Cosmology, Panoramic Biology, and Panoramic Psychology
2015The convergence of astronomy and biology produces astrobiology. When astrobiology extends its range of concern beyond planets and stars to the whole universe, astrobiology converges with cosmology.

EXTRAORAL AND PANORAMIC SYSTEMS
Dental Clinics of North America, 2000Digital solutions for extraoral and panoramic radiology have been available for more than 15 years. The costs, however, have been too high for adoption in private dental practice. The past 2 years have seen tremendous growth in the number of relatively cost-effective digital options available to the dentist and dental specialist.

Intraoral or Panoramic Radiography?
Dental Clinics of North America, 1984When panoramic radiographs are used to replace full-mouth radiographic series for the pediatric patient, certain advantages and disadvantages of this technique should be understood. The panoramic exposure offers ease of operation, shorter working time, and greater coverage than does the intraoral full-mouth series.

2019 IEEE Conference on Virtual Reality and 3D User Interfaces (VR), 2019
The dynamic motion of fluids is essential in generating aesthetically appealing effects like the oriental ink painting and fluid art. Due to the prohibitively high cost required in volumetric fluid simulations, implementing an interactive volumetric painting system in immersive virtual environments (IVEs) is challenging.

Clinical Obstetrics and Gynecology, 1983
The method of CO2 panoramic hysteroscopy was described. It can be performed as an office procedure without the need for preliminary cervical dilatation or even a paracervical nerve block. The risks are minimal, and the benefits of being able to see the uterine cavity are manifold.

Panoramic radiograph in pathology
Atlas of the Oral and Maxillofacial Surgery Clinics, 2003The panoramic radiograph is an excellent extraoral radiograph to reveal abnormalities and pathologic conditions of the jaws and to show calcification of adjacent soft tissue. A single panoramic radiograph provides a significant image of the maxillofacial skeleton and dentition and often is used as a survey or screening film because of the area it ...

Normally, modeling 3D face is an effective way for pose-invariant recognition, yet its expensive computation significantly discourages potential applications. In this paper, a simple and fully automatic panoramic image-based pose-invariant face recognition method is proposed to present excellent accuracy with low complexity. In this paper, a face shape

Panoramic mosaicing optimization
14th International Conference on Image Analysis and Processing (ICIAP 2007), 2007Motorized dome-type cameras, also called PTZ camera, allow the creation of panoramas. These panoramas represent the whole of the scene seen by the camera. In the case of a PTZ camera and with certain constraints, the scene seen by the camera can be considered as a sphere.
