Looping in a spiral
...zy at first (some loops only get executed once) but step by step I'll make transformations until we arrive at 4 pairs of loops that are identical and hence can be replaced with a single pair placed inside of another loop.
This will provide us with a general solution of computing n iterations without...
Principal component analysis in Python
...his; methods use the current value.
Methods:
The methods of class PCA transform vectors or arrays of e.g.
20 variables, 2 principal components and 1000 observations,
using partial matrices U' d' Vt', parts of the full U d Vt:
A ~ U' . d' . Vt' where e.g.
U' is 1000 x 2

You can find a nice OpenCV code example in Java, C++, and Python on this page: Features2D + Homography to find a known object
Both algorithms are invariant to scaling and...
