This presentation demonstrates 3D aware panoramic imagery and its use in mixed reality applications. Recent data scanning technologies are capable of producing 3D aware panoramic images of large scale outdoor environments. These datasets, collected and stored in global geo-coordinates, consist of 360 degree panoramic imagery and real-world shape from LiDAR laser scans. The resulting imagery and...

A key component in most virtual reality systems is the ability to perform a walkthrough of a virtual environment from different viewing positions and orientations. Recent advances in image-based rendering techniques allow us to have interactive panoramic viewing of real world environment using real photos. With panorama visualization tools like QuickTime VR, we are able to have fast navigation ...

The 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 covers. The panoramic radiograph does not provid...

Multi-resolution techniques have been used in a wide range of vision applications. Unfortunately, the costly operation of building a proper pyramid strongly reduces its value as a tool for reducing computational cost. A new approach, physical panoramic pyramid, is introduced in this paper. Physical panoramic pyramid measures multiple resolutions simultaneously resulting in multi-resolution pano...

OBJECTIVE: The present study was aimed at comparing indices obtained from dental panoramic radiographs with bone densitometry results in the identification of individuals affected by osteoporosis/osteopenia. MATERIALS AND METHODS: Panoramic mandibular, mental, antegonial, gonial and mandibular cortical indices calculated with basis on dental panoramic radiographs of postmenopausal women were co...

OBJECTIVE To evaluate the detection of mucous retention cyst of maxillary sinus (MRCMS) using panoramic radiography and cone beam computed tomography (CBCT). STUDY DESIGN A digital database with 6,000 panoramic radiographs was reviewed for MRCMS. Suggestive images of MRCMS were detected on 185 radiographs, and patients were located and invited to return for follow-up. Thirty patients returned...

PURPOSE This study was performed to determine the prevalence of maxillary canine impaction on a basis of a single panoramic radiograph in Bangladeshi population. MATERIALS AND METHODS A random sample of seven hundred panoramic radiographs was collected from the patient record of a dental clinic. All the selected panoramic radiographs were taken from January 2009 to August 2010 by a single pan...

This paper proposes an affine motion compensated prediction (AMCP) method to predict the complex changes between the successive frames in panoramic video coding. A panoramic video is an image-based rendering (IBR) technique [1] which provides users with a large field of view (e.g. 360 degree) on surrounding dynamic scenes. It includes not only the translational motions but also the non-translat...

BACKGROUND One of the most frequent concerns encountered in dental implant treatments is inadequate pre-operative planning. Panoramic radiographs are readily accessible and cost efficient. The aim of this study is to assess the accuracy of vertical measurements in mandibular molar and premolar region on panoramic radiography. MATERIALS AND METHODS Panoramic radiographs were made of a partiall...
