An OpenCV framework for iOS and macOS.

Needed iOS 8.0+.

Needed macOS 10.10+ and OpenCV 2.4.x.

Install OpenCV by using Cocoapods.

cd EMCVLib
pod install

Install OpenCV with brew:

We cannot use brew to install OpenCV due to this issue: [OpenCV #7833]

It'll crash when releasing camera in Cocoa application.

So we need to compile it by ourselves.

• Download OpenCV: [trmbhs/opencv]
• Download extra modules: [trmbhs/opencv_contrib]
• Config with cmake-gui. See here.
• Make and install.

Headers should be here:

/usr/local/include/opencv

/usr/local/include/opencv2

Librarys should be here:

/usr/local/lib

Download the repo. Then drag the framework project to your project.

What can this framework does now?

• Display image and play real-time processing video with customized filter.
• Color convert. Channals split. Image flip, smooth, blending.
• Edge Detection. Find extreme values and locations. Calculate and compare histograms.
• Corener Harris. Shi-Tomasi. Optical Flow.
• Matching algorithm: Template Match. Back Projection. SURF Match.

Some screenshots of the demo.

Use @autoreleasePool when doing loop can solve some memory problems.
