The stacks were resliced with a factor of four along the z-axis. 3D maximum intensity projections were generated with Fiji (projection method: brightest point, 360° rotation angle, angular increments were set at 1° or 10°). The multi-view registration and fusion of the organoid stack ...

Additionally, we use 𝜇(⋅)μ(⋅), 𝜎(⋅)σ(⋅), 𝛾(⋅)γ(⋅), and 𝛽(⋅)β(⋅) to respectively denote the accumulated mean, standard deviation, learned scaling factor, and bias for each branch in the BN layer. We have also defined symbolic representations for the...
In this study, the dilation factor in the dilated convolution layers of the parallel block was set to 2, and appropriate padding was applied to maintain the same input and output size. The features extracted from the parallel block are then forwarded to the convolution attention block, which ...
Still, using the NLM filtered images, the internal land parcel boundary area appeared to have a “dilation” (Figure A1-paddy-g\g’) or “erosion” (Figure A1-water-g\g’, corn-g) phenomenon. In areas with relatively high BC values, abnormal “high-value squares” appear after NLM ...
Joint estimation of image rotation angle and scaling factor. In Proceedings of the 2021 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), Tokyo, Japan, 14–17 December 2021; IEEE: Piscataway, NJ, USA, 2021; pp. 1716–1721. [Google Scholar] ...
A common factor limiting the usability of both DMPs and DAPs is the lack of efficient means for handling the massive input-data size. The memory load and computation-time of standard iterative methods increase linearly with respect to both input image size and the number of scales used [8,...
A three-phase source converter transforms the 500 V DC to 260 V AC and keeps the unity power factor. To connect the converter to the grid, a 100 (kVA) 260 (V)/25 (kV) three-phase coupling transformer is employed. Figure 7. Schematic of a parallel system on a direct bus. 3.2. ...
