I'm working on some image processing tasks and I'm required to calculate the 'shift vector' of two feature vectors. I'm not entirely sure what 'shift vector' really means as i just came across it, but googling gave me pretty much irrelevant searches and just recently i came across this source, which i assume is mathematically defined 'shift vector'. http://www-history.mcs.st-and.ac.uk/~john/geometry/Lectures/A4.html
I would like to know what shift vector really does and how do i calculate the shift vector of two similar vectors.
If i have two vectors(made up),
$v_1 = (43, 20, 10)$
$v_2 = (40, 16, 8)$
Note: normally, the image feature vectors can be represented in the form:
first_feature = [34 30 10 15 27 67]
second_feature = [30 28 6 13 25 60]
Is there any formula that i could use to calculate the shift vector between the two vectors above?
I'm totally new to vectors and would appreciate some help on this.
