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 ...
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 ...
Fractal analysis of eroded surfaces by digital image processing
(Elsevier B.V., 2002-10-01)
Jet impingement erosion test rig has been used to erode titanium alloy specimens (Ti-4Al-4V). Eroded surface profiles have been obtained by vertical sectioning method for light microscopy observation. Mixed fractals have ...
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 ...
Classification of polymers insulators hydrophobicity basead on digital image processing
(ABM, ABC, ABPol, 2012)
Although the hydrophobicity is usually an arduous parameter to be determined in the field, it has been pointed out as a good option to monitor aging of polymeric outdoor insulators. Concerning this purpose, digital image ...
A Practical Approach for Segmentation of Twigs on Samples of Yerba Mate by Digital Image Processing
(Institute Of Electrical And Electronics Engineers, 2013-02)
This paper discusses the implementation of the digital image processing techniques as a method for estimating the contents of twigs in samples of yerba mate. The hardware used in this paper, to obtain the analyzed images, ...
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 ...
Um estudo sobre o osu do modelo de cor RGB no proceso de correspondência por correlação
(2007-01-01)
Image matching is one of the most important processes in Digital Photogrammetry, since it allows the automation of several stages of the photogrammetric pipeline. In most of the commercial software nowadays available, the ...
