Filtering is aneighborhood operation, in which the value of any given pixel in the output image is determined by applying some algorithm to the values of the pixels in the neighborhood of the corresponding input pixel. A pixel's neighborhood is some set of pixels, defined by their locations ...

The single-layer meta-processor enables a large variety of mathematical operations, including spatial shifting, high-order derivative, spectral filtering and other Fourier transform algorithms. In the following, we will show two exemplary important applications of image detection. Fig. 3: Design of ...
Given CellTrek’s internal filtering mechanism (see the ‘Benchmarking analysis with simulated datasets’ subsection), we provided all cells in the corresponding scRNA-seq atlases as input (without duplication or downsampling). For Visium samples, we ran CellTrek (version 0.0.0.9000) with default ...
