Crack marking in RC experiments is not only a labor intensive job but also carries a certain level of risk. Some cracks are too thin to be detected by edge-detection based methods. Public available image analysis software ImPro Stereo developed by the authors of this paper estimates the surface deformation by using image analysis. New formula has been added into ImPro Stereo in this work to estimate...
Image processing and analysis is a potential tool for monitoring of activated sludge wastewater treatment plant. One of the important parameters to track the performance of activated sludge plant is sludge volume index (SVI). In this paper, image analysis based modeling is used to estimate the sludge volume index. Bright field microscopic images of activated sludge were segmented by integrating four...
This paper presents the characterization of cracks in a metallic material using an eddy current testing technique called alternating current field measurement (ACFM). This technique has already shown good results in the field of defect detection because, the current is forced to flow in a uniform direction, making it more predictable and easy to interpret the behavior of the induced current when a...
