Intro and loading Images - OpenCV with Python for Image and Video Analysis 1

Welcome to a tutorial series, covering OpenCV, which is an image and video processing library with bindings in C++, C, Python, and Java. OpenCV is used for all sorts of image and video analysis, like facial recognition and detection, license plate reading, photo editing, advanced robotic vision, optical character recognition, and a whole lot more.

We will be working through many Python examples here. Getting started with OpenCV's Python bindings is actually much easier than many people make it out to be initially. You will need two main libraries, with an optional third: python-OpenCV, Numpy, and Matplotlib.

Thanks to your tutorials on OpenCV i created a traffic sign recognition program on raspberry pi2 in about 5 hours or so. your tutorials are easy simple to understand and show how to use examples in daily applications. will share the code here in a month or so. thanks for all the help.

Dear lord finally got this all to work so far!, installing opencv for 64bit to work inside pycharm in 2018...wow!! Here's the crazy part, after several hours of nothing but forum reading and trial and error and teaching myself new things I decided I'm going give up on trying to make it work with pycharm and just use python idle. Then two days later and several hours of tinkering more I some how have it working in pycharm but not python Idle. Go figure.

After some hard work i got it to work by doing:
pip3 install opencv-python
sudo apt-get install libatlas-base-dev
sudo apt-get install libjasper-dev
sudo apt-get install libqtgui4
sudo apt-get install python3-pyqt5
sudo apt-get install libqt4-test


Then i could import cv2

[tariktahaozdogan]

your briefing in some intervals are really helpful and important. One like opencv's default BGR but matplotlib's is RGB. This can save a homework like mine :)

[pratimugale]

For python3 what worked for me was:
$ python3 -m pip install opencv-python
$ python3 -m pip install matplotlib

[milosulipeck]

honestly Im just thankful that you helped me install opencv
