pylops.signalprocessing.ConvolveND(N, h, dims, offset=(0, 0, 0), dirs=None, method='fft', dtype='float64')[source]¶ ND convolution operator.
Apply n-dimensional convolution with a compact filter to model (and data) along a set of directions
dirsof a n-dimensional array.Parameters: - N :
int Number of samples in model
- h :
numpy.ndarray nd compact filter to be convolved to input signal
- dims :
list Number of samples for each dimension
- offset :
tuple, optional Indices of the center of the compact filter
- dirs :
tuple, optional Directions along which convolution is applied (set to
Nonefor filter of same dimension as input vector)- method :
str, optional Method used to calculate the convolution (
directorfft).- dtype :
str, optional Type of elements in input array.
Notes
The ConvolveND operator applies n-dimensional convolution between the input signal \(d(x_1, x_2, ..., x_N)\) and a compact filter kernel \(h(x_1, x_2, ..., x_N)\) in forward model. This is a straighforward extension to multiple dimensions of
