### Comparing two sequences of events for similarity

Suppose I have two sequences of unequal lengths whose elements are timestamps of discrete events in milliseconds: $S_1 = \{150, 200, 700, 1300, 2500\}$, $S_2 = \{300, 670, 900, 1300\}$. These ...

### Best large gaussian filter for current SIMD instruction sets?

I'd like to make a faster version of the Gaussian blur for Inkscape. Here's what I found various open source projects use: librsvg: 3 box blurs when stdev > 2. Else, separable FIR filter. Krita:  ...

### Confusion with Complex Gaussian process with Auto-covariance

I have a complex sequence $z(t)$ in time which I know to be a Gaussian process. I read that the complex Gaussian process is not only characterized by the covariance, but also the pseudo-covariance ...

### The Effect of the Finite Radius of Gaussian Kernel

Page 168 of Digital Image Processing, Global Edition says: we know that the values of a Gaussian function at a distance larger than 3𝜎 from the mean are small enough that they can be ignored. If we ...

### How to upscale an image using a Gaussian filter in R?

I want to resample a raster from 15m to 460m using a Gaussian filter. The goal I am having a coarse image which I want to downscale. I also have a fine resolution band to assist the downscaling. The ...

### What is the outcome of applying a derivative on X and Y for an image? and Other Gaussian Questions

I've been diving into smoothing kernels and I came up with a lot of questions that I haven't been able to find in the internet. If you can I'd appreciate the help :) (Capitals and bold were used for ...
