Image rejects in digital skeletal radiography in two public hospitals in Norway
(Journal article; Peer reviewed, 2023)Introduction The proportion of diagnostic images not applied for diagnostic purposes is an indicator of image quality, safety, and efficiency in radiography. Despite increased awareness, image reject is still a substantial ... -
Image rejects in general direct digital radiography
(Peer reviewed; Journal article, 2015)Background: The number of rejected images is an indicator of image quality and unnecessary imaging at a radiology department. Image reject analysis was frequent in the film era, but comparably few and small studies have ... -
Image Restoration and Super-resolution using Total Variation
(Master thesis, 2019)Hovedformålet med bildegjenoppretting er å kunne hente informasjon fra ødelagte kilder til bildedata. Hovedmålet med denne oppgaven er å undersøke en kraftig metode for bildegjenoppretting, og det er å bruke variasjonsalgoritmer ... -
Image segmentation and multivariate analysis in two-dimensional gel electrophoresis
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:200, Doctoral thesis, 2007)The topic of this thesis is data-analysis on images from two-dimensional electrophoretic gels. Because of the complexity of these images, there are numerous steps and approaches to such an analysis, and no “golden standard” ... -
Image Segmentation of Corrosion Damages in Industrial Inspections using State-of-the-Art Neural Networks
(Master thesis, 2020)Denne masteroppgaven studerer avanserte bildesegmenteringsalgoritmer for automatisk korrosjonsskade-segmentering. Automatisk bildeanalyse er nødvendig for å prosessere all data som samles inn med dronebaserte industrielle ... -
Image Statistics as Glossiness and Translucency Predictor in Photographs of Real-world Objects
(Peer reviewed; Journal article, 2020)We interpret our surrounding based on the visual stimuli, and perceive objects and materials around us to have various attributes, like color, glossiness, and translucency. We analyze the three-dimensional world based on ... -
Image Techniques for Identifying Sea-Ice Parameters
(Journal article; Peer reviewed, 2014)The estimation of ice forces are critical to Dynamic Positioning (DP) operations in Arctic waters. Ice conditions are important for the analysis of ice-structure interaction in an ice field. To monitor sea-ice conditions, ... -
Image texture and radiation dose properties in CT
(Journal article; Peer reviewed, 2016)The aim of this study was to compare image noise properties of GE Discovery HD 750 and Toshiba Aquilion ONE. The uniformity section of a Catphan 600 image quality assurance phantom was scanned with both scanners, at different ... -
Image Texture, Uniformity, Homogenity and Radiation Dose Properties in CT
(Master thesis, 2013)In medical imaging, especially when potentially harmful X-ray radiation is used to obtain diagnostic data, it is important to reduce the risk the patient is exposed to. For that reason it is expected to obtain maximum ... -
Image-based and risk-informed detection of Subsea Pipeline damage
(Peer reviewed; Journal article, 2023)As one of the most important assets in the transportation of oil and gas products, subsea pipelines are susceptible to various environmental hazards, such as mechanical damage and corrosion, that can compromise their ... -
Image-Based Bidirectional Reflectance Measurement of Non-Diffuse and Gonio-Chromatic Materials
(Doctoral theses at NTNU;2019:344, Doctoral thesis, 2019)Visual appearance of packaging material can vary in terms of perceived colour or lightness properties with a change in illumination and viewing directions mainly due to its optical properties. This gives a desirable visual ... -
Image-based Estimation of Physical Correlates of the Visual Appearance of Snow
(Doctoral theses at NTNU;2024:69, Doctoral thesis, 2024)The most common representation of snow is to describe it as a white and cold powder material that is usually found in winter or specific areas of the world. It can also be associated with the Christmas festivities, winter ... -
Image-based goniometric appearance characterisation of bronze patinas
(Journal article; Peer reviewed, 2021)Patinas are a form of metal polychromy used to decorate metallic artworks. Due to the nature of the metallic surface, their colour and gloss is perceived differently when the illumination and viewing directions vary. Sparkle ... -
Image-Based Recognition of Individual Trouts in the Wild
(Journal article; Peer reviewed, 2019)Individual fish recognition has potentials in applications as fish cultivcation and fishing tourism. Unlike previous research, which either based on physical marker or based on photograph comparison using observers, this ... -
Image-based Somatotype as a Biometric Trait for Non-Collaborative Person Recognition at a Distance and On-The-Move
(Peer reviewed; Journal article, 2020)It has recently been shown in Re-Identification (Re-ID) work that full-body images of people reveal their somatotype, even after change in apparel. A significant advantage of this biometric trait is that it can easily be ... -
