I have been using the picamera for a few days, and the picamera Python library. I have exhausted the picamera image effect library options. I am looking for effects such as warp, and distort. Can this be done easily with the picamera library, or what library can I import to do things like warp, and distort images?
Such kind of image processing requires an advanced image processing library. One of the most popular and used library is OpenCV. You can build and compile your own OpenCV or just download the regular library.
To build and compile your own OpenCV, you can follow up my cheat sheet. I am not using Virtual Environment. If you want to install it in virtual environment you can also follow the PyImageSearch well organized tutorial.
If installing the regular library type one of these two commands.
for Python 2:
sudo apt-get install python-opencv
for Python 3:
sudo apt-get install python3-opencv
Also the answer to your question is the same as my answer here.
