Step 2: Saving the size of the input image in pixels. Step 3: Get the Fourier Transform of the input_image. Step 4: Assign the Cut-off Frequency. Step 5: Designing filter: Ideal High Pass Filter. Step 6: Convolution between the Fourier Transformed input image and the filtering mask.

Web16 de mai. de 2015 · Now that's much better. Now we'll get onto your filtering mechanism. Your Butterworth filter is slightly incorrect. The meshgrid of coordinates is slightly wrong. The -1 operation that's at the ending interval needs to go outside: [x y]=meshgrid (-floor (w/2):floor (w/2)-1,-floor (h/2):floor (h/2)-1); Remember, you are defining a symmetric ...
