Adding third party libraries to an OpenCV project on Xcode

Question

I am new to the XCode environment so apologies if this sounds trivial.

I am trying to use a third party library using for OpenCV that helps me do some blob analysis, CCL etc. Hosted here

I have searched a lot but there doesn't seem to be much documentation on how to go about adding and using these new libraries. I am using XCode 4.5.2, OpenCV 2.4.2.

When I simply add all the header files to the project folder and #include them in the source code, it fails to compile. I have also tried adding the "Header Paths" but it doesn't help. What am I missing?

I have tried to follow the instructions (compiling it using the terminal but it doesn't compile too) I am not clear on how or when exactly to use CMAKE.

Any help will be appreciated. Thank you.

I would suggest you using CvBlob on google code which is different from the one on willowgarage, I have got recently confused with this so take a look at this question for alternative blob analysis libraries.

Moreover, CvBlob has also a good support community here. (Search on "[cvblobslib]" or on "[blob] [opencv]")

Thank you I ended up using the SimpleBlobDetector class and it seems to work fine. Although its a little slow with 640x480 images, resizing them solves the issue. More info on SimpleBlobDetector here :http://stackoverflow.com/questions/8076889/tutorial-on-opencv-simpleblobdetector – anirudhr Dec 03 '12 at 23:37
Great! I've thought you'd like to see alternatives. Can you please indicate with voting-up or accepting if my answer was useful? – Barney Szabolcs Dec 03 '12 at 23:40

Try this: cvBlob: OSX installation

Once you get it compiled, you need to include the library under Link Binary with Libraries in Build Phases. (This screenshot shows the core, imgproc, and highgui libraries. Your cvBlob library would go in the same place.)

This was great, I was able to install cvBlob and generate `libcvblob.dylib` there is another error within it. For now I have resorted to using the `SimpleBlobDetector`class. – anirudhr Dec 03 '12 at 23:39
