I read through the documentation and: 1\. I can't figure out what the default it is if you don't set it (did I miss it in the docs somewhere?) 2\. What does it do? Does it take the bounding box and reduce and it and only use those pixels? [upl-image-preview url=https://discuss.luxonis.com/assets/files/2024-05-24/1716559883-118940-image.png] Is there a better place for documentation? The methods are defined but they don't really say what they do? For instance "min" for the calculation algorithm, is it actually the minimum of all pixel values? Or is this some kind of a histogram? Same goes with the pixel step, what is the default?

Default is 1.

Correct. It's used for calculating spatials for each detected object. Since we normally don't want the whole detection bbox used in averaging the values for depth (background is also captured which disturbs the measurement), you can specify the scaling factor so the smaller roi is taken for SpatialLocationCalculator to ensure more accurate depth of the object.

Takes the minimum.

Step size 1 is default. If you want to speed up the calculations you can use other steps.
