  OpenCV released OpenCV-3.4.4 and OpenCV-4.0.0 on 20th November. There have been a lot of bug fixes and other changes in these versions. The release highlights are as follows:

  • OpenCV is now C++11 library and requires C++11-compliant compiler. Minimum required CMake version has been raised to 3.5.1.
  • A lot of C API from OpenCV 1.x has been removed.
  • Persistence (storing and loading structured data to/from XML, YAML or JSON) in the core module has been completely reimplemented in C++ and lost the C API as well.
  • New module G-API has been added, it acts as an engine for very efficient graph-based image procesing pipelines.
  • dnn module now includes experimental Vulkan backend and supports networks in ONNX format.
  • The popular Kinect Fusion algorithm has been implemented and optimized for CPU and GPU (OpenCL)
    QR code detector and decoder have been added to the objdetect module.
  • Very efficient and yet high-quality DIS dense optical flow algorithm has been moved from opencv_contrib to the video module.

  In this post, we will provide a bash script for installing OpenCV-4.0.0 (C++ and Python 3.7) on macOS – High Sierra and Mojave. We will also briefly study the script to understand what’s going in it. Note that this script will install OpenCV in a local directory and not on the entire system. Let’s jump in 🙂

  If you are still not able to install OpenCV on your system, but want to get started with it, we suggest using our docker images with pre-installed OpenCV, Dlib, miniconda and jupyter notebooks along with other dependencies as described in this blog.

  1. Install XCode

  Install XCode from App Store.

  All you must do is remember your LastPass master password, and LastPass autofills web browser and app logins for you.Get started today for free and join the millions managing passwords with LastPass — you’ll wonder how you lived without it!NEW TO LASTPASS?Download LastPass now and get started, completely free. Chrome for mac and 1password4. From your LastPass vault, you can store passwords and logins, create online shopping profiles, generate strong passwords and more.

  If XCode available on App Store is not compatible with your OS:

  1. Find XCode version compatible to your OS from this table https://en.wikipedia.org/w/index.php?title=Xcode#Version_comparison_table
  2. Go to this webpage https://developer.apple.com/download/more/
     • Login if you have apple developer account else create your account and login.
     • Search for xcode and download the version compatible to your OS.
  3. Install XCode.
  4. After installation open XCode, and accept xcode-build license when it asks.

  2. Install OpenCV

  Now that XCode has been installed, we will move on to OpenCV installation.

  First, let’s install Homebrew.

  We will also add Homebrew to PATH.

  Next we will install the requirements – Python 3, CMake and Qt 5.

If you encrypt an internal device, you must enter a password to access the device and its information. How to password protect usb for use in mac and windows.

  We will also save current working directory in cwd variable and OpenCV version (master) in cvVersion.

  Now, let’s install the Python libraries and create the Python environment.

  Next, let’s clone the OpenCV github repositories.

  Finally, we will use CMake to build OpenCV.

  And that’s it! By now you should have OpenCV installed successfully in your system.

  3. Test OpenCV Installation

  3.1. OpenCV in Python

  To use cv2 module in Python, we will first activate the Python environment.

  Next, let’s import the module and verify the OpenCV Version installed.

  3.2. OpenCV in C++

  To use OpenCV in C++, we can simply use CMakeLists.txt and specify the OpenCV_DIR variable. The format is as follows:

  Make sure that you replace OpenCV_Home_Dir with correct path. For example, in my case:

  Once you have made your CMakeLists.txt, follow the steps given below.

  

  This will generate your executable file in build directory.

  Hope this script proves to be useful for you :). Stay tuned for more interesting stuff. In case of any queries, feel free to comment below and we will get back to you as soon as possible.
