Webscipy can be compared to other standard scientific-computing libraries, such as the GSL (GNU Scientific Library for C and C++), or Matlab’s toolboxes. scipy is the core package for scientific routines in Python; it is meant to operate efficiently on numpy arrays, so that numpy and scipy work hand in hand. WebFigure 1.6: Another example of Wiener filtering. Wiener filters are comparatively slow to apply, since they require working in the frequency domain. To speed up filtering, one can take the inverse FFT of the Wiener filter G(u,v) to obtain an impulse response g(n,m). This impulse response can be truncated spatially to produce a convolution mask.
