A photogrammetric method for single image orientation and measurement
(2005-06-01)
The aim of this paper is to present a photogrammetric method for determining the dimensions of flat surfaces, such as billboards, based on a single digital image. A mathematical model was adapted to generate linear equations ...
Evaluation epidermal p53 immunostaining by digital image analysis
(2013-02-01)
Digital techniques have been developed and validated to assess semiquantitatively immunohistochemical nuclear staining. Currently visual classification is the standard for qualitative nuclear evaluation. Analysis of pixels ...
Conceptual representation of digital medical images: Integrating Context and Visual Content
(Univ Complutense Madrid, Servicio Publicaciones, 2016-01-01)
This paper presented a proposal conceptual framework to represent digital medical images, which is integrated: 1) descriptive elements from the rules of cataloging and metadata standards for information resources, 2) ...
Generating virtual images from oblique frames
(2013-04-01)
Image acquisition systems based on multi-head arrangement of digital camerasare attractive alternatives enabling a larger imaging area when compared to a single framecamera. The calibration of this kind of system can be ...
Edge detection in digital images using fuzzy numbers
(2009-09-15)
The purpose of this paper is to introduce a new approach for edge detection in grey shaded images. The proposed approach is based on the fuzzy number theory. The idea is to deal with the uncertainties concerning the grey ...
Assessment of manipulation accuracy of digitized occlusal radiographic images--sub and over exposure.
(2009-12-01)
The aim of this study was to evaluate whether digitized images obtained from occlusal radiographs taken with low or over dose of radiation could be improved with the aid of computer software for digital treatment. Thirteen ...
Quantitative fractography by digital image processing: NIH Image macro tools for stereo pair analysis and 3-D reconstruction
(Blackwell Science, 2001-10-01)
A set of NIH Image macro programs was developed to make qualitative and quantitative analyses from digital stereo pictures produced by scanning electron microscopes. These tools were designed for image alignment, anaglyph ...
Comparison between inverted and unprocessed digitized radiographic imaging in periodontal bone loss measurements
(2007-11-01)
The advances in digital imaging technology in dentistry have provided an alternative to film-based radiography and have given new options to detect periodontal bone loss. The purpose of this study was to compare inverted ...
Effect of alternative photostimulable phosphor plates erasing times on subjective digital image quality
(British Inst Radiology, 2010-01-01)
Objective: To evaluate the influence of alternative erasing times of DenOptix (R) (Dentsply/Gendex, Chicargo, IL) digital plates oil subjective image quality and the probability of double exposure image not Occurring.Methods: ...
Online Mammographic Images Database for Development and Comparison of CAD Schemes
(SPRINGER, 2011)
Considering the difficulties in finding good-quality images for the development and test of computer-aided diagnosis (CAD), this paper presents a public online mammographic images database free for all interested viewers ...
