Automated diagnosis of human intestinal parasites using optical microscopy images
Intestinal parasitosis constitutes a serious health problem in most tropical countries. The diagnosis of enteroparasites in laboratory routine relies on the examination of stool samples using optical microscopy and the ...
Evaluation epidermal p53 immunostaining by digital image analysis
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 ...
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 ...
Automatic segmentation of digital images applied in cardiac medical images
The digital image processing has been applied in several areas, especially where it is necessary use tools for feature extraction and to get patterns of the studied images. In an initial stage, the segmentation is used to ...
A photogrammetric method for single image orientation and measurement
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 ...
