WebAug 29, 2024 · Python Scipy Butterworth Vs Gaussian Filter Higher frequencies in the image are highlighted by high pass filters. The original image is then combined with the high pass image to create a sharper image. It could be interesting to play around with the Butterworth or Gaussian high pass filters’ width and frequency threshold. Web$\begingroup$ "Design a digital FIR filter, of length 1001, where the gain at DC is 0 (silence), and all frequencies up to filter_stop_freq 70 Hz are also blocked, then the gain can rise up to filter_pass_freq 100 Hz, where the gain should be 1 (should be passed unchanged), and the gain from there up to the Nyquist frequency should stay flat at 1. Then use this filter on …
