...would be to extract features (keypoints) using the scale-invariant feature transform (SIFT) or Speeded Up Robust Features (SURF).
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...

How to resize an image with OpenCV2.0 and Python2.6
... is deprecated in SciPy 1.0.0, and
will be removed in 1.2.0. Use skimage.transform.resize instead.
Note that if you're looking to resize by a factor, you may actually want skimage.transform.rescale.

Generate random numbers using C++11 random library
...distribution.
Programmers often introduce nonrandomness when they try to transform
the range, type, or distribution of the numbers generated by rand.

Correct use for angular-translate in controllers
...red for every single string on the page, which not only is a slower way to transform the page but can slow down all the actions on the page, if you start adding large numbers of events to it.
Anyway, using a post-processing translation platform makes more sense to me. Using GlobalizeIt for examp...
What is a Context Free Grammar?
...hree, {000, 001, 010, 011, 100, 101, 110, 111}.
Grammars work by defining transformations you can make to construct a string in the language described by a grammar. Grammars will say how to transform a start symbol (usually S) into some string of symbols. A grammar for the language given before is:...
Best way to work with dates in Android SQLite [closed]
...s in all the SQL statements. It's far easier to define an utility class to transform text to Date objects inside your Java program. But always remember that SQLite transforms any date value to UTC+0000.
In summary, despite the general rule to always use the correct data type, or, even integers deno...
