What are the important points to be noted while asking a question so that everyone understand it very well and help them to reproduce the problem and have contributions?

Similarly what to take care while answering questions ?

( Hi, this is a community wiki question, I think there should be an article like this, but there is not. So I request the OpenCV developers to point out some important matters in this topic )

Since I got granted wiki rights yesterday, I will start to convert important topics here into wiki pages on Github and then we can link from here. That makes it more easier to update them and keep track of the information.

While asking a Question :

  • Before asking, Use site search to find whether your question is already asked.
  • If you have very small doubts on already asked subject, you can use comments there, but if doubt is much bigger, you can ask another question giving reference to previous question
  • Be Precise to the point. Please open your question with a brief explanation on what you want. Do not place your question at the very end!
  • It is also good practice to mention your OS, 32/64 bit, OpenCV version etc in your question
  • Since most of the questions are related to computer-vision or image processing, you can add a sample image to your question (may be add an image of output you needed, for eg, if object detection, just draw a boundary around the object to be detected using any paint tool). This way, people may more grasp on your question.
  • If your reputation is low to add an image, you can upload image in any image hosting services (like and provide link here.
  • Take maximum care to use simple, plain English. ( If other language users find difficulty with English, they can use It may be useful to some extent)
