Opencv Snippets for Vs Code

This Vs Code extension provides the user with Opencv snippets in python. It helps in effectively providing, refactoring and editing the opencv projects in python3. All the snippets starts with "o", so typing a letter o gives recommendation for all the available opencv snippets.
Example -

This Example detects corner in the image.

example1

This Example detects shapes in the image.

example2

From the examples above, it can be easily seen that how easy and fast it become to code in Opencv by using this extension. It also saves you from any syntactical mistakes and increase your coding speed by many folds.

Installation:

This Extension can be installed from the Visual Studio Code Marketplace or by searching within VS Code.

In VS code press ctrl+p and type ext install extensionName and press enter.

Requirements

Python3 should be installed in the system.

For installing python latest version you can head over to python offcial website.

Opencv library of python. This can be installed by executing the following command in the terminal or cmd.

    pip install opencv-python

Numpy library of python. This can be installed by executing the following command in the terminal or cmd.

This need not be compulsorily installed but it is advised to install it because there are various snippets which require this library for better and smooth performance.
