Remember to free image memory after using it!Īnd there you go. If( !cvSaveImage('my_image_copy.png', pInpImg) )įprintf(stderr, 'failed to write image file ') Write the image to a file with a different name, PInpImg = cvLoadImage('my_image.jpg', CV_LOAD_IMAGE_UNCHANGED) įprintf(stderr, 'failed to load input image ') Load an image from file - change this based on your image name

Example showing how to read and write images This is where the header files for OpenCV were built. Change the path to /usr/local/include.Click on the project file and go to “Build Settings”.Feel free to move them to a separate group within your project. If you know what you need, you can obviously pick and choose. To prevent linker errors, I recommend you initially add ALL the files ending in “…2.3.1.dylib”. When Finder pops up, hit “/” to bring up the navigation panel.To do this, right click on the project, and click “Add files to.” dylib files provided by OpenCV into our project. Start a new XCode Command Line Tool project.So we now have OpenCV built but we still have to link to the framework in our project.

This should now build OpenCV into your /usr/local/ directory. Type in the following: # make a separate directory for building In terminal, navigate to the folder where OpenCV was extracted to. We are going to build OpenCV using cmake. You can check to see that cmake is installed by typing cmake in a new terminal window.

This will go fetch cmake and its dependencies and install them onto your system. Unzip it after you download it into a folder. You can check to see if it installed successfully by opening your terminal and typing port. Also you will need XCode installed for any of this to work (but you knew that, right?)

Also, I tested this on OSX Lion, but it should apply to Snow Leopard or Leopard. Note: This method does not set up the Python bindings for OpenCV (still working on that). Now that I’ve got it set up, I decided to write this little post to explain to others how to go about setting it up. There are various ways to install it – through package managers such as Homebrew or Macports, or through the tarball + cmake. I had to look through a whole bunch of different sites to figure out what to do. I’m using OpenCV for my 4th year design project and setting it up was a huge pain.
