Digital image analysis

The capillary rise on a Wilhelmy plate (Section II-6C) is a nice means to obtain contact angles by measurement of the height, h, of the meniscus on a partially immersed plate (see Fig. 11-14) [111, 112]. Neumann has automated this technique to replace manual measurement of h with digital image analysis to obtain an accuracy of 0.06° (and a repeatability to 95%, in practice, of 0.01°) [108]. The contact angle is obtained directly from the height through...

Digital image analysis directly gives the size distributions and a mean diameter, d. All other morphological characteristics are calculated with this mean diameter and the model shown in Fig. 20. 

The results of image analysis of macroporous epoxies showing a narrow and bimodal pore size distribution are summarized in Table 3. The volume fraction, ( ), is always calculated from density measurements. The validity of the data obtained with digital image analysis is of utmost importance in order to draw correct conclusions concerning the structure-property relationships. 

Martens and Thybo (2000) used digital image analysis of scanning electron microscope images of potato tissue and of starch to successfully relate microstmcture characteristics to textural properties.

Low levels of LA are found in the sebum of acne sufferers,200 and levels appear inversely related to sebum secretion rate.201 It has been hypothesized that this local EFA deficiency may lead to the follicular hyperkeratosis and occlusion of acne, and that an increased supply of linoleate might possibly ameliorate the condition.202 In support of this, digital image analysis revealed that topical application of LA over a one month period reduced the size of microcomedones.203 Decreased levels of LA may also contribute to acne inflammation by failing to inhibit phagocytosis and ROS generation by neutrophils.204...

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.

Digital image analysis will increase the number of usable dyes since it does not rely on the human eye for detection and differentiation. A digital image is acquired at excitation wavelengths relevant for the dyes applied, and separate detectors record individual colors. Thus, digital image analysis e.g. will allow the combination of fluorescent and immunoenzyme dyes.
