When I use the default method L2-Norm in cv::BFMatcher on an own defined descriptor, is it irrelevant which position every value in my descriptor vector has?
So when I have a descriptor vector (1, 1, 2, 2, 6, 8, 4, 5, ...) according to http://mathworld.wolfram.com/L2-Norm.html it should have the same L2-Norm as (6, 2, 5, 4, 2, 8, 2, 1, 1...).
When I would use NORM_HAMMING is the position then relevant? Am I right or completely confused?
