Very efficient and yet high-quality DIS dense optical flow algorithm has been moved from opencv_contrib to the video module.QR code detector and decoder have been added to the objdetect module. The popular Kinect Fusion algorithm has been implemented and optimized for CPU and GPU (OpenCL).dnn module now includes experimental Vulkan backend and supports networks in ONNX format.New module G-API has been added, it acts as an engine for very efficient graph-based image procesing pipelines.Persistence (storing and loading structured data to/from XML, YAML or JSON) in the core module has been completely reimplemented in C++ and lost the C API as well.A lot of C API from OpenCV 1.x has been removed.
Minimum required CMake version has been raised to 3.5.1. OpenCV is now C++11 library and requires C++11-compliant compiler.But I want to run opencv sample code using Qt Thanks in advance. I am able to run opencv code using terminal. Can anybody have a sample or some documentation regarding running opencv code using Qt on Mac where opencv is installed using macports? I have searched a lot forum but have not found any proper documentation or steps. For example, download source code of OpenCV, cd to its directory and run the command in console: python samples/python2/browse.py Ilya Lysenkov (Sep 20 '12) edit The Homebrew formula for opencv is messed up as of today it doesn't install Python bindings. If you don’t have homebrew on your system you can download and install it from here. First of all, try to reach the point where you can run OpenCV python samples without error. The quickest and easiest way to install OpenCV on your mac is to use Homebrew.
