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

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.

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.

Signal Processing: Image Communication, 2003
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.

The 2nd Canadian Conference on Computer and Robot Vision (CRV'05), 2005
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.

Digitalization represents increasing opportunities and challenges for enterprises. One challenge is to adequately evaluate their environment and its influence towards their strategy. This paper describes the Panoramic Lens, a new model that assesses and rates social, economic, and environmental factors of influencing the digital transformation of an ...

Limitations of panoramic radiography
Oral Surgery, Oral Medicine, Oral Pathology, 1968Abstract Oral panography is a valuable and simplified procedure which can supply helpful and even essential information in a variety of situations encountered in daily practice. Lack of clarity of the image projected on the film contraindicates complete reliance on this procedure when image sharpness is essential, as it usually is. As a supplement to

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.
