Linear filtering is a powerful image enhancement method that involves modifying part of the signal frequency spectrum using a linear and shift-invariant filter, resulting in output images characterized by the c

No bandpass filtering was performed (see Supplementary Note 1). Finally, we removed participants from further analysis if any of their four resting-state scans had excessively large head motion, defined by having frames with >0.2 mm frame-wise displacement or a derivative root mean square ...

For small-amplitude excitations, Spintorch solves an inverse problem for the linear wave equation—it designs a magnetic-field distribution that performs a desired linear operation (such as matrix multiplication, convolution, pattern matching, and spectral analysis, matched filtering) as we will show ...
Linear sampling –Texture sampling method when we fetch a footprint of 2×2 texels and we apply a bilinear filter to aquire the final color information (aka GL_LINEAR filtering). Gaussian filter The image space Gaussian filter is an NxN-tap convolution filter that weights the pixels inside of...
For time-invariant linear transforms such as cross convolution or matched filtering, the transversal filter provides a highly parallel computational module with high throughput and minimal control overhead. This paper will show how similar computational modules can be configured to provide similar ...

Signal filtering and smoothing. Calculating moving averages in time-series analysis. Additional Tips: For element-wise multiplication in the frequency domain (closely related to convolution), use Fourier Transform via np.fft.fft. If you need multi-dimensional convolution, explore scipy.signal.convolve...
