A real-time data acquisition system for precision agricultural is presented. Using the system, the spatiotemporal data for the specific local area can be collected at small expense. A hardware frame is designed to take synchronized multi-view images of the target plants as well as environmental data. To monitor the growth of plants or crops, set of images are taken periodically and a multi-view stereo...
Electrical capacitance tomography (ECT) is a noninvasive imaging reconstruction technique to visualize cross-sectional permittivity distribution of dielectric objects inside a domain, which is based on the measured capacitance on the electrodes mounted on the periphery. Numerous iterative image reconstruction methods have been developed to accelerate convergence rate and to enhance the quality of...
In general, image reconstruction algorithms for electrical capacitance tomography (ECT) can be classified into iterative and noniterative algorithms. Iterative algorithms produce better quality images however they can only be used off-line due to intensive computational burden. In the context of computational burden, in this paper we propose a fast noniterative image reconstruction algorithm called...
We introduce a method to align the angle of reference beam holographic data storage by using a photodiode in front of image sensor, the brightness of information data can be easily extracted. From the output of the photodiode, we can quickly find the optimal angle for readout beam
