Constructing a rich and continuous visual experience requires computing specific details across views as well as integrating similarities across views. In this paper, we report functional magnetic resonance imaging (fMRI) evidence that these distinct computations may occur in two scene-sensitive regions in the brain, the parahippocampal place area (PPA) and retrosplenial cortex (RSC). Participa...

Linear array CCD-based panoramic cameras are being used also in measurement applications. The elegant image acquisition mode and the high information content of those images make them suitable candidates for quantitative image analysis. The best possible accuracy is acquired by a suitable sensor model and following the concept of network design. In our previous investigations we designed a sens...

In this article, we present some development results of a system that performs mosaicing (or mosaicking) of panoramic faces. Our objective is to study the feasibil­ ity of panoramic face construction in real-time. To do so, we built a simple acquisition system composed of 5 stan­ dard cameras which, together, can take simultaneously 5 views of a face at different angles. Then, we chose an eas­ ...

The aim of this study was to evaluate the accuracy of imaging methods for detection of apical periodontitis (AP). Imaging records from a consecutive sample of 888 imaging exams of patients with endodontic infection (1508 teeth), including cone beam computed tomography (CBCT) and panoramic and periapical radiographs, were selected. Sensitivity, specificity, predictive values, and accuracy of per...

In this paper some applications of motion analysis are investigated for a compact panoramic optical system (Panoramic Annular Lens). Panoramic image acquisition makes multiple or mechanically controlled camera systems needless for many applications. Panoramic Annular Lens’ main advantage to other omnidirectional monitoring systems is that it is a cheap, small, compact device with no external hy...

BACKGROUND/OBJECTIVE Panoramic and periapical radiographs are normally used in impacted third molar teeth surgeries. The aim of the present study was to evaluate and compare the distortion of the erupted third molar teeth on panoramic and periapical radiographs. PATIENTS AND METHODS A total of 44 radiographs were obtained of 22 patients (age range, 18-24 years) referred to the faculty of dent...

BACKGROUND AND AIMS Panoramic radiographs are used for surgical planning of unerupted third molars. The major prob-lems associated with panoramic radiography include unequal magnification and geometric distortion of the image. The purpose of this study was the clinical evaluation of the effect of radiographic distortion on the position and classification of unerpted mandibular third molars. M...

During the last few years, innovative optical design strategies to generate and control image mapping have been successful in producing high-resolution digital imagers and projectors. This new generation of panoramic lenses includes catadioptric panoramic lenses, panoramic annular lenses, visible/IR fisheye lenses, anamorphic wide-angle attachments, and visible/IR panomorph lenses. Given that a...

PURPOSE Preoperative radiographic assessment of the mandibular third molars is essential to prevent inferior alveolar nerve damage during extraction. The purpose of this study was to assess the reliability of panoramic signs of association between the roots of teeth and the canal, and to compare the panoramic signs with cone beam computed tomography (CBCT) findings. MATERIALS AND METHODS CBCT...

OBJECTIVE To report the association of pulp calcification with that of cardiovascular disease (CVD) using digital panoramic dental radiographs. MATERIALS AND METHODS Digital panoramic radiographs of patients referred from the angiography department were included if the patient was under 55 years old and had non-restored or minimally restored molars and canines. An oral and maxillofacial radio...
