Nice writeup. I use these filters quite often (especially the particle filter). Very powerful tools.

- personjerry 11y agoIn what context do you use them?
- yarou 11y agoThey're used quite extensively in GPS/positioning.
- makmanalp 11y agoBasically situations where you have a few data sources for the same thing, all with their own margins of error, update rate, etc. And you want to combine them to get one better data point. Eg in robotics, you can put together GPS, vision (e.g. from visual markers or perceived movement) and wheel encoder (how many times did the wheel spin, where do I think I am based on that) data to get one much more accurate location point.
- tnecniv 11y agoRobotics in different contexts. I've used two different styles of Kalman filter for cleaning up data from computer vision based pose/velocity estimation. I also used a particle filter as a way of tracking humans in thermal images from a camera on a UAV.
