Adaptive electrical capacitance volume tomography(AECVT) provides further flexibility to the imaging process in comparison to conventional electrical capacitance volume tomography(ECVT), which is an important research direction of electrical capacitance tomography(ECT). Aiming at the problem that time of computation for AECVT, a new sampling strategy for AECVT in which only includes those capacitance...
In the application of particle holography analysis, the diameter measurement is basic and important. A novel approach of segmentation is proposed. For improving the accuracy of measurement, the method of bi-threshold is used firstly and then the edge linking method is adopted to get the more accuracy segmented particle image. The experiment tests showed the less relative error is in the diameter measurement...
An approach of image segmentation was used in the application of particle holography analysis for the diameter measurement. The whole process of image segmentation based on boundary detection was delivered. For improving the accuracy, the segmented particle image has been obtained by the bi-threshold method which decreases influence of background noise and inhomogeneous gray distribution of holography...
