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.

AbstractMany video sequences consist of a locally dynamic background containing moving foreground subjects. In this paper we propose a novel way of re‐displaying these sequences, by giving the user control over a virtual camera frame. Based on video mosaicing, we first compute a static high quality background panorama. After segmenting and removing the

This paper presents a new method of camera calibration for a panoramic stereovision sensor based on cylindrical projective geometry. The panoramic sensor allows us to get peripheral information about unknown environments, the architecture simplifies computation considerably. The device needs no calculation of epipolar lines.

Panoramic Ultrasound of the Thyroid
Thyroid, 2003Panoramic ultrasound is a technical modification of conventional ultrasound that produces images with a large anatomic field of view. Images obtained with this technique display both lobes of the thyroid gland on a single image, and provide an accurate imaging representation of a variety of thyroid disorders.

An immersive experience where one views imagery captured from a panoramic camera with a head mounted display (HMD) or "cave" display system is an example of image processing that would be appreciated by the masses. In such a system, a user can see what would be seen from several viewpoints in a natural way by simply moving their head around.

Abstract In this paper, the problem of constructing the whole view of a scene background from an image sequence is considered. First, point or block correspondence between each pair of successive frames is determined. Three parametric motion models are used: 2-D translation with scale change, affine, and projective.

AbstractThis article presents an approach to SLAM that takes advantage of panoramic images. Landmarks are interest points detected and matched in the images and mapped according to a bearings‐only SLAM approach. As they are acquired and processed, the panoramic images are also indexed and stored into a database.

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
