Filtering tutorial/instructions suggestions

[lukehshaw]

Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

1. What is the offset threshold parameter? Your description is a bit vague. Is this a standard deviation threshold, for example?
2. If I wanted to conduct my own comparisons of various filters what is the best way to do this?
3. Random question: after triangulation are outputs automatically converted into real space (mm for example rather than pixels?)
4. Random suggestion: offer an option to define points in space to establish a ground plane. I, for example, work in an arena and have trained my network to identify corners of the arena. It would be nice to have coordinates automatically rotated accordingly.

Describe the solution you'd like

1. Descriptions of config parameters that are better suited for someone who is not familiar with the package.
2. Suggestions for how to deploy different filters, how to modify filtering parameters, and how to use outputs that have been filtered with different parameters for comparisons. Thanks!

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

Furthermore clarification of things like this (from triangulation parameters) such as range, what's going on, etc. would be very helpful in your documentation.

scale_smooth: Strength of enforcement of the smoothing constraints. scale_length: Strength of enforcement of the spatial constraints.
