Image quality enhancement in digital panoramic radiograph
One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...
متن کاملEvaluation of Image Magnification in Digital Panoramic Radiography
Introdouction: The aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. Materials and methods: In this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. Implant diameter and length were measured on pan...
متن کاملPanoramic Image Stitching
Faculty of Computer Science by Kai Wang Pengbo Li Panoramic image stitching is an active research topic and lots of methods was developed to achieve a nice stitched panorama under different limitation of raw pictures. For example, pictures need to be aligned properly, pictures need to has same exposure level, or pictures need to be horizontal or vertical in space. In this project, we followed t...
متن کاملPanoramic Image Acquisition
This paper is concerned with acquirinig panoramic focused images using a small field of view video camera. When scene points are distributed over a range of disiances from the sensor, obtaining a f o c w e d composite image involves focus computations and mechanically changing some sensor parameters (translation of sensor plane, panning of camera etc.) which can be time intensive. In this paper...
متن کاملPanoramic Image Stitching
This thesis investigates the panoramic image stitching problem in computer vision area. The panoramic image stitching algorithms are divided into image alignment and image stitching approaches. The former can find the correspondence relationships among images with certain degrees of overlap, while the latter takes the correspondence relationships estimated by the registration algorithm and uses...
