Hello everyone,

I understand that the HaarDetectObjects function based on Viola-Jones algorithm takes in consideration different window scales so I guess it is scale invariant. But Nothing being said about rotation invariance, I read that it's possible to make it rotation invariant by choosing the right Haar features (for example 4x rotated features by 45 degrees). But is it done by default in the provided XML file.

Also, I would like to know, if it is symmetry invariant. For example, training on profiles of people looking to the right will work on people looking to the left ?

Thanks in advance.
