HYPERSPECTRAL PANORAMIC IMAGING [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Abstract. Hyperspectral instruments are designed for the characterisation of planetary surfaces, oceans and the atmosphere. At the moment there are a number of aircraft systems and planned space missions. Examples for this are the hyperspectral missions for Earth remote sensing (EnMAP) and also for deep space and planetary missions (Mercury mission ...

Optical approach of a hypercatadioptric system depth of field [PDF]

open access: yes, 2010
A catadioptric system is composed of a mirror and a perspective camera. Since the mirror is curved and the distance between the mirror and the camera is short, some parts of the panoramic image keep blurred.

Virtual viewpoint three-dimensional panorama [PDF]

open access: yes, 2014
Conventional panoramic images are known to provide for an enhanced field of view in which the scene always has a fixed appearance. The idea presented in this paper focuses on the use of the concept of virtual viewpoint creation to generate different ...

Foreign body reaction granuloma mimicking an aggressive tumor of the mandible

open access: yesClinical Case Reports, 2023
Inflammatory granuloma caused by a vegetable foreign body is a lesion that can develop in the oral cavity. It results from the implantation of vegetable matter, leading to an inflammatory reaction and the development of bone resorption.

Deep Learning for the Radiographic Detection of periodontal Bone Loss [PDF]

open access: yes, 2019
We applied deep convolutional neural networks (CNNs) to detect periodontal bone loss (PBL) on panoramic dental radiographs. We synthesized a set of 2001 image segments from panoramic radiographs. Our reference test was the measured % of PBL.
