A customized acrylic-resin template with gutta percha markers was fabricated for a human cadaver mandible. Twelve measurements were made between gutta percha markers and between the markers and known mandibular anatomic locations. Periapical, panoramic, and computerized tomographic radiographs were taken of the mandible and stent. Similar readings were recorded from the radiographs. The average...

A practical way for obtaining depth in computer vision is the use of structured light systems. For panoramic depth reconstruction several images are needed which most likely implies the construction of a sensor with mobile elements. Moreover, misalignments can appear for non-static scenes. Omnidirectional cameras offer a much wider field of view than the perspective ones, capture a panoramic im...

The jaw has traditionally been evaluated by dentists and oral surgeons using conventional panoramic and intraoral films. Recently, CT software programs specifically developed to evaluate dental implant patients have provided radiologists with a new look at the mandible and maxilla. The anatomy seen on these reformatted panoramic and cross-sectional images is complex, and our objective is to def...

Due to the simplicity and efficiency of panoramic image representation, it has been successfully applied to Internet applications to provide an immersive illusion within a real or synthetic environment. However, once a scene has been captured as image, the lighting condition can no longer be adjustable. As the illumination adjustment is one key capability in computer graphics, we describe in th...

Panoramic imaging is becoming an increasingly important tool in the areas of mobile robotics and machine vision. In the area of panoramic stereo imaging for range measurements two views of the one scene can be captured by a single camera using a discontinuous mirror surface. It is critical in this case to optimise mirror shapes for this application. In this paper, the needs of panoramic stereo ...

The demonstration described hereafter covers technical work carried out in the FascinatE project [1], related to the interactive retrieval and rendering of high-resolution panoramic scenes. The scenes have been captured by a special panoramic camera (the OMNICAM) [2] with is capturing high resolution video featuring a wide angle (180 degrees) field of view. Users can access the content by inter...

Osteoporosis characterized by low bone mass/osteopenia can be identified using radiomorphometric indices in routine panoramic radiographs. This study estimates the prevalence of osteopenia in 50-80 years age group, using panoramic mandibular index (PMI), mental index (MI) and mandibular cortical index (MCI). PMI, MI and MCI were applied on 36 panoramic radiographs; MI and MCI were compared with...

Video surveillance [1] technology plays an important role in the security field, with its intuitive, convenient and abundant information and is widely used in city traffic, civil security and other various fields especially in the important safety departments or major events. In this paper, according to the video surveillance system features and functional requirements, we use embedded system, ...

ISSN: 2186-1390 (Online) http://www.ijcvsp.com Abstract In building panoramic images, the selection of appropriate homography plays a crucial role in reducing the error and in registering the images accurately. In this paper, we demonstrate a method for selecting the appropriate homography for building the panoramic image based on information extracted from the images. It is shown that using ho...

OBJECTIVE To determine the prevalence of preeruptive intracoronal dentin defects in Chinese children from panoramic radiographs, and describe the imaging characteristics of these lesions. METHODS A total of 707 panoramic radiographs with 8,171 unerupted permanent teeth were examined. Each unerupted tooth was examined with regard to the absence or presence of radiolucencies within the dentin o...
