EMCVLib

An OpenCV framework for iOS and macOS.

Usage

Needed iOS 8.0+.

Needed macOS 10.10+ and OpenCV 2.4.x.

iOS: Install OpenCV for iOS

Install OpenCV by using Cocoapods.

cd EMCVLib
pod install

macOS: Install OpenCV for macOS

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.

Headers should be here:

/usr/local/include/opencv

/usr/local/include/opencv2

Librarys should be here:

/usr/local/lib

Install the framework

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

Functions

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.

Screenshots

Tips

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