Creating a low pass filter
WebJun 18, 2024 · First, you need a time constant for your filter from the cutoff: alpha = dt / (RC + dt) and cutoff = 1 / (2 * pi * RC). You need this factor to compute the next filtered value: def low_pass (x_new, y_old, cutoff=20): alpha = dt / (dt + 1 / (2 * np.pi * cutoff)) y_new = x_new * alpha + (1 - alpha) * y_old return y_new From wikipedia: low-pass. WebJan 18, 2014 · As far as I know, the formula to generate the Gaussian low-pass filter is: [x y] = meshgrid (round (-N/2):round (N/2), round (-N/2):round (N/2)); GaussianFilter = exp ( (-x.^2/ (2*sigma^2)-y.^2/ (2*sigma^2))); What should the formula for the high-pass filter be in this case? matlab image-processing Share Improve this question Follow
