title: opencv python documentation
body: <p>Recently, I want to use the <code>OpenCV</code> library in <code>Python</code>, but the documentation of <code>Python</code> binding of <code>OpenCV</code> is very unclear and insufficient. I want to ask where to find some detailed documentation of <code>Python</code> binding of <code>OpenCV</code>. Previously I used <code>OpenCV</code> in <code>C++</code>, and the documentation is very helpful, more over I can go to the source code of it where I was in doubt. But the source code of <code>Python</code> binding doesn't provide much information, I think. For example, it takes me a long time to find out that the <code>CV_8UC1</code> flag is in the module <code>cv2.CV_8UC1</code>, but the flag <code>CV_CAP_PROP_FPS</code> is in the module <code>cv2.cv.CV_CAP_PROP_FPS.</code></p>
