### Layman Description of the Kalman Filter

In "traditional" filters the design specifications like gain and bandwidth drive the structure of the filter. This is because with these filters we are interested in transforming a signal ...

### Remove Wave Patterns from an Image Using Inpainting

expanding on knut's idea and advise, I have written a script that achieves what knut did in Python also trying to fix the black squares in the corners of the image. ...

### Remove Wave Patterns from an Image Using Inpainting

As Knut says, as a first cut I'd just use simple filtering. Looking at the frequency domain of your original image: it's a bit hard to see, but there are two peaks just above and below the central DC ...

### Remove Wave Patterns from an Image Using Inpainting

If it is just «amplitude modulation» can you identify the vertical periodic pattern and multiply with the inverse? Doing inpainting seems excessive as there seems to be real detail in the dark wave ...

### Derive the filter mask that corresponds to the double filtering process

The convolution is associative: $(I * f_1) * f_2 = I * (f_1 * f_2)$. In other words, applying the two filters in sequence to an image is equivalent to applying the convolution of the two filter ...

Assuming we're dealing with a linear filter, we can use deconvolution to find the kernel. Usually, deconvolution operations estimate the original input image $f$ in the operation $f*h=g$, given the ...
