Detection of symmetries in Python

Question

I want to detect symmetries (rotation, translation, etc) of a simple figure or a shape in a image. That is, if I find one symmetry I want to replicate my original figure with it.

Are there any function or module? I have thought in python-opencv, but I did not find nothing.

Answer 1

Let me just throw some packages at you: OpenCV for Python Cookbook might be a good start. A search for "opencv" on the Python Package Index yields several bindings of OpenCV for Python.

Concerning the detection of symmetries: The answer to question how to detect simple geometric shapes using OpenCV? might be a good start. After you find similar objects, check their orientation. Replacing then should be a piece of cake.
