Introduction: Opencv and Python Installation for Windows / Mac

OpenCV is an open source computer vision library which is very popular for performing basic image processing tasks such as blurring, image blending, enhancing image as well as video quality, thresholding etc. In addition to image processing, it provides various pre-trained deep learning models which can be directly used to solve simple tasks at hand. The programmers have to download and load the model using OpenCV instructions in order to do the task of inference on their own dataset.

Firstly, you need to install OpenCV library in your system prior to using it for your own dataset. At this stage, there can be two pathways of installing OpenCV in your system namely – (a) Using pip (b) Source Installation. pip is the package manager which is used to install the packages written in python. The difference between installing a python package from source and through pip are given in the table:

Step 1: Download OpenCV

Click on the below link to redirect to the latest release web page of OpenCV.

for windows: https://sourceforge.net/projects/opencvlibrary/fil..

for MAC: https://sourceforge.net/projects/opencvlibrary/fil..

Step 2: Download OpenCV-contrib

As you can see in the image above, Click on Sources button to download OpenCV – 4.1.0 archive files into your system. Once the download is complete, unzip the files at your desired location. For illustration purpose, I am going to create a folder named as ‘opencv’ in my Desktop and I will unzip the downloaded archive inside the same folder.

In order to download OpenCV_contrib you must open the command line tool and clone the repository by executing the following command:

for windows: https://github.com/opencv/opencv_contrib

then click on Clone / Download

for Mac: git clone https://github.com/opencv/opencv_contrib.git

Step 3: Python Installation

Python doesn’t come prepackaged with Windows /mac, but that doesn’t mean Windows/mac users won’t find the flexible programming language useful. It’s not quite a simple as installing the newest version however, so let’s make sure you get the right tools for the task at hand.

First released in 1991, Python is a popular high-level programming language used for general purpose programming. Thanks to a design philosophy that emphasizes readability it has long been a favorite of hobby coders and serious programmers alike. Not only is it an easy language (comparatively speaking, that is) to pick up but you’ll find thousands of projects online that require you have Python installed to use the program.

Which Version Do You Need?

Unfortunately, there was a significant update to Python several years ago that created a big split between Python versions. This can make things a bit confusing to newcomers, but don’t worry. We’ll walk you through installing both major versions.

When you visit the Python for Windows download page, you’ll immediately see the division. Right at the top, square and center, the repository asks if you want the latest release of Python 2 or Python 3 (2.7.13 and 3.6.1, respectively, as of this tutorial).

Step 4: Pip Command Installation

After the python installation

go to this url: https://bootstrap.pypa.io/get-pip.py

Now open terminal / command prompt : type python get-pip.py

OpenCV 4.1.1 is the best software free for educational or even commercial purposes. The OpenCV stands for Open Source Computer Vision. Its initial version is launched in June 2000. The second major release was in October 2009. Its latest version 3.3.0 comes out in the marketplace on 3 August 2017. It is a library of programming functions for real-time computer vision. This is a perfect program that was originally written in C language and consisting full C++ interface. It is also available in a full Python interface. It supports almost all the operating systems such as Windows, MAC, and Windows.

The program also has a GUI command which will assist you in managing your Windows and handle input files. It composed of many languages like Python, C++ and JAVA interfaces. It is mainly used by users for digital image processing. This is used in the latest lab work of research work related to digital image processing. Also, it detects specific objects such as faces, eyes, cars, in the videos or images. You can use 2D and 3D toolkits. The Libraries composed are very helpful to process real-time data. It should be used in facial and gesture recognition systems. It also includes statistical machine learning libraries that may include Boosting, Decision Tree Learning, etc.

In OpenCV, a video can be read either by using the feed from a camera connected to a computer or by reading a video file. The first step towards reading a video file is to create a VideoCapture object.

I have trawled through all of Google's and Stack Overflow's search results in order to install stupid OpenCV on my Mac and all the methods have been completely useless.

I started trying to do this with OS X 10.8 and its XCode version and it didn't work. Now I'm on 10.9 and XCode 5.0.1.

I have tried mainly 2 methods:1) Downloading the .dmg file from OCV website and doing the CMAKE routine. When I get to the make -j8 step, at around 36% it gives me errors such as:

-make[1]: * [modules/imgproc/CMakeFiles/opencv_perf_imgproc.dir/all] Error 2

-Documents/Libraries/opencv-2.4.6.1/modules/ts/include/opencv2/ts/ts_perf.hpp:480:12: note: expanded from macro 'CV_PERF_TEST_MAIN_INTERNALS' while (++argc >= (--argc,-1)) {VA_ARGS; break;} /this ugly cons.. ^ ~~1 error generated.make[2]: ** [modules/imgproc/CMakeFiles/opencv_perf_imgproc.dir/perf/perf_main.cpp.o] Error 1

Download Opencv Contrib

2) Using Homebrew at the end of which, even if I added the python path, when I do 'import cv' it gives me a 'no module named cv' error

I tried Macports as well a while ago so I don't remember the steps, but it didn't work.

It goes without saying that I've tried different versions of OCV and all have given me issues at the make step.

Any other solutions?

There is a great tutorial located here. It highlights that the version you are trying to use 'is not compatible'. I am thinking that you should try installing the version stated in those instructions and see how you go.

The following instructions are taken directly from that link:

INSTALLING CMAKE

1. First you need to download the .dmg file under Binary Distribution of CMake here. At the time of I installed this, the file name is cmake-2.8.11.2-Darwin64-universal.dmg.

2. Upon completion of the installation you will be prompted whether to put CMake in /usr/bin, select Yes and finish installation

3. To ensure that CMake has been successfully installed, type cmake -version in Terminal

INSTALLING OPENCV

Download Opencv Package

1. First, download the tar file of OpenCV 2.4.3 stable version here and DO NOT use the latest version. I struggled with the installation because I used OpenCV 2.4.6.1 and it's not yet compatible.

2. Extract the tar file in a folder and go to that folder through the terminal, e.g. cd Downloads/OpenCV-2.4.3

3. Now, each of the following line is to be executed in Terminal and must be executed successfully (no error)

   1. mkdir build
   2. cd build
   3. cmake -G 'Unix Makefiles' .
   4. make -j8
   5. sudo make install

4. You are all set to use OpenCV!

Steps for those who prefer to build opencv from source

I prefer to use cmake-gui instead of entirely doing this from command line, since that gives you more idea about the options available for opencv configuration and bring you in better position if you want to customize opencv build tomorrow ( like enabling java wrapper or OpenCL etc ).

1. Download source either from opencv.org(1) or opencv githubrepo(2)
2. Start cmake-gui.
3. Set source path to downloaded opencv directory and build path toyour choice and click Configure button.
4. Specify generator as unix makefiles and pressContinue
5. Choose compilers and click Done button.
6. An options page with errors might be listed.

7. Hovering mouse over any option gives a tooltip about the option. Edit option(s) as you feel fit. E.g.
   CMAKE_INSTALL_PREFIX - change opencv install path
   BUILD_SHARED_LIBS - build static or shared library. etc

Then click Configure again. If there are still errors, edit the option(s) causing the error and click Configure button. Repeat the edit / Configure cycle until there are no more errors. Once there are no more errors, proceed to step (8).

A minimal sample config of the WITH tab below. Feel free to play with options. This might cause build problems initially. But your understanding of build, will be better.

8. Click Generate to generate make files.
9. Type make ( in terminal at build folder )
10. Type make install
