Opencv Install For Mac
OpenCV is basically an OpenSource library having the best frameworks for video processing. In an OSX project, we had to implement OpenCV libraries in Swift language for MAC application. This article covers, how OpenCV libraries are used in a Linux/MAC application.

Following are the steps to be followed: 1- Download latest OpenCV source code for Linux/MAC OS from this. 2- Once OpenCV source code download completes, extract the OpenCV directory and save it at some location. This will be the raw code of OpenCV and you have to build it. 3- Now you need to check if cmake is installed on your MAC machine or not by typing “ cmake” command in terminal. If it is not installed, type “ sudo port install cmake” in terminal for installing cmake tool in your MAC machine. If cmake tool is already installed on your MAC then jump to next step.

4- In terminal, navigate into the OpenCV directory and type the following commands: mkdir build cd build cmake –G “Unix Makefiles”. 5- Now you need to wait till terminal does its processing. Once the process finish, type the following command in terminal: make –j8 sudo make install It will prompt you for MAC login and password. Once you enter the password and give it a go, terminal will install some dependencies from the Internet and will install some dynamic libraries in /usr/local/include and /usr/local/lib directory on your MAC machine.
Let the process finish successfully. 6- Now open Xcode and make a new project to add OpenCV libraries in your OSX application project. Press ( Alt + Cmd + a) or select ( File- Add Files to project) option from menu. A window will open in Xcode. Type /usr/local/lib and press “ Go” Button.

The /usr/local/lib directory will open. 7- Select the required OpenCV libraries and press “ Add” Button. You need to make sure that you are including the proper library, not the shortcut file.
The OpenCV libraries naming convention is as libopencv.dylib. Now select the following OpenCV libraries and press “ add” button: libopencvhighgui.3.0.0 libopencvvideoio.3.0.0 libopencvcore.3.0.0 8- The selected OpenCV libraries will start showing in Xcode. It is recommended to group the items under some suitable name. 9- Now you need to select the project from Xcode navigator from the left menu and go to “ Build Phases” tab. Select “ Link Binary with Libraries” and then add the OpenCV libraries that you included in the project (as in previous step).
10- Again select the project from Xcode navigator from the left menu and go to “ Build Settings” tab. Type “ Header Search Path” in the Search.
Now add /usr/local/include path in “ Header Search Path” and set it to recursive. 11- Once again you need to select the project from Xcode navigator from the left menu and go to “ Build Settings” tab. Type “ Library Search Path” in the Search and add /usr/local/lib path in “ Library Search Path” and set it to recursive. You are ready to build your OSX project now and it should be built without any issue.
CPP Code in Xcode: OpenCV code will be done in CPP and you will have to make wrapper of CPP code in Objective-C. Later on, you can use Objective-C code in Swift language via objective-c bridging header. To add CPP code in Xcode, you need to follow more steps:. To create CPP Header File, Select ( File-New-File) and select Header File. You need to give an appropriate name to it as VideoSilicing.h. Add the code.
UPDATE: Mavericks users were likely frustrated for the last few weeks trying to install OpenCV. It appears the problem has been fixed, and these instructions should work without issue.
My is one of the most popular on this site (which is simultaneously surprising and fantastic). However, I recently switched from using to – users that need to migrate existing installs can. Still complicated but thoroughly do-able, here is how to install OpenCV on a Mac running Mountain Lion:. Open Applications Utilities Terminal. Install Homebrew by into Terminal.
Not having much success with installing SimpleCV on iMac and Mavericks Have followed above and others. I think I am close. Very grateful for any suggestions.
Big kiss for the correct one.

Worked for me too! I’m using Mac OS X 10.9.3. The only hiccup was installing XCode.

I didn’t realize I needed that. I was prompted to install the command line XCode tool during the install, but I stopped and did the full install of XCode from the App Store and started over. Setting up the path at the end required some different steps, but I just followed the instructions supplied by the installer: If you need Python to find the installed site-packages: mkdir -p /Library/Python/2.7/lib/python/site-packages echo ‘/usr/local/lib/python2.7/site-packages’ /Library/Python/2.7/lib/python/site-packages/homebrew.pth Thanks!:-).
