Computer-aided image analysis

This calculation is tedious to perform for each particle of a distribution even with the advent of computer aided image analysis. Faster techniques simply measure a linear dimension parallel to some fixed direction and assume that the particles are oriented randomly so that these measurements average out when a sufficiently large population has been sized. Several linear dimensions typically are used. Ferefs diameter is the mean value of the distance between pairs of parallel tangents to the projected outline. Martin s diameter is the mean cord length of the projected outline of the particle. In addition, the maximum... 

At present it is not possible to relate the properties of paste to the morphology of hydration products, because of their diversity and variability. Wittmaim [46] is of the opinion that the statistical approach to this problem, with help of the computer aided image analysis of microscopic observations, can give the quantitative charac-teristies of different paste microstructure.

For the estimation of Chi formation in hairy roots, the root cells were examined on a laser scanning confocal image system attached to a microscope. The filter package with a laser (excitation 568 nm) and a 590-610 nm band pass barrier filter for red fluorescence was employed. Digital image analysis was performed by a computer-aided image processing system with software. 

Several approaches have been done to quantify membrane morphology parameters from SEM images. The first attempts were made in the early 1990s. They permitted more quantitative information to be obtained from membrane SEM micrographs and they showed the potential power of computer-aided SEM analysis [30, 31]. More recentiy, other approaches based on different model equations have been reported [32, 33]. The IFME software [32], was developed by our research group within the past years and permits numerical results of the main morphological parameters to be obtained from SEM micrographs. 

Computer-aided diagnosis (CAD) has been defined as a diagnosis made by a radiologist who uses the output of a computer analysis of the images when making his or her interpretation. There are two main types of CAD systems. One is computer-aided detection...
