WebThe density pore can identify those less populated areas while the chamber pore is able to quantify the size of empty patches observed in the spread powder bed. Applicability of this approach is demonstrated via both simulation-generated and experimentally spread powder layers. Sensitivity tests on the sampling parameters are conducted. WebThis study derived a segmentation method based on a convolutional neural network, U-Net, and a large-scale database consisting of 7039 brain T1-weighted MRI data samples. We evaluated the method by using three experiments focused on four distinct topics, namely, the necessity of preprocessing steps, cross-institutional and longitudinal reproducibility, …
