In MATLAB, there is a command fir1 that generates the filter coefficients but how to calculate low pass filter's coefficients in OpenCV? I need to use a low pass filter with 50th order, hamming window and cutoff frequency = 0.00000000001. Also, I can't use filter2D command because I'm doing 1D filtering just like low pass filtering of an audio signal (eample).
