Detailed Description

apply an FIR filter to an image

vspline has some code which isn't useful only for b-splines. One example is the application of a FIR filter to a MultiArrayView. With vspline's multithreaded SIMD code, this is done efficiently. This example program will apply a 1D kernel along the horizontal and vertical. You can pass an arbitrarily long sequence of filter coefficients after an image file name.

compile with: ./examples.sh fir.cc

invoke passing an image file and the filter's coefficients. the result will be written to 'fir.tif'
