Nowadays, with rapid advancement of technology, people can roam around the virtual world through the aid of the Internet. One of these advances is a photographic technique called panoramic view where images are captured with elongated field of view using specialized software or equipments. However, the computational cost of generating a panoramic view is high. One of the popular software for ge...

Mosaicing and super resolution are two ways to combine information from multiple frames in video sequences. Mosaicing displays the information of multiple frames in a single panoramic image. Super-resolution uses regions which appear in multiple frames to improve resolution and reduce noise. Simple combination of the two methods is problematic since the alignment used for mosaicing may not be a...

The aim of this study is to develop an efficient and practical method of a direct mapping of a panoramic projection on an unfolded prism and pyramid polyhedral projection surface with the aid of a computer. Due to the fact that straight lines very often appear in any architectural form we formulate algorithms which utilize data about lines and draw panoramas as plots of functions in Mathcad sof...

PURPOSE This study was performed to determine the relative frequency of positioning errors, to identify those errors directly responsible for diagnostically inadequate images, and to assess the quality of panoramic radiographs in a sample of records collected from a dental college. MATERIALS AND METHODS This study consisted of 1,782 panoramic radiographs obtained from the Department of Oral a...

background the gonial angle is one of the most important measurements required for orthodontic treatment and orthognathic surgery. it is difficult to determine the accurate measurement of each gonial angle on cephalometric radiographs because of superimposition of the left and right angles. objectives the aim of the present study was to determine the right and left gonial angles on panoramic ra...

Panoramic radiographs are frequently applied in dental radiodiagnostics and might serve as a tool for identification of a subject's bone mass. Only in a few publications can data on men, younger subjects and larger groups of patients be found. No such data are available for the Polish population; therefore, the aim of the study was to determine normal ranges of panoramic radiomorphometric param...

Most of the existing panoramic cameras have cylindrical field of view (FOV) which has a 360 width in azimuth, but a limited height in elevation. However, a hemispherical (or near spherical) FOV is highly desirable in many applications such as robot navigation and surveillance. This paper presents a planarmirror-based panoramic camera (HEM) which is capable of acquiring nearly hemispherical FOV ...

Background and Aim: To compare the radiographic distance from the inferior part of mandibular second and third molars to the superior border of mandibular canal on radiographs obtained by conventional periapical radiographs, intraoral photostimulable phosphor plate (Intraoral PSP) and panoramic photostimulable phosphor plate (Panoramic PSP). Subjects and Methods: The study was carried out on 25...

OBJECTIVES Radiographic examination is one of the most important parts of the clinical assessment routine for temporomandibular disorders. The aim of this study was to compare the diagnostic accuracy of cone-beam computed tomography(CBCT) with panoramic radiography and spiral computed tomography for the detection of the simulated mandibular condyle bone lesions. STUDY DESIGN The sample consis...
