We will also briefly study the script to understand what’s going in it.
In this post, we will provide a bash script for installing OpenCV-4.0 (C++ and Python 3.5) on Ubuntu 16.04.
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.There have been a lot of bug fixes and other changes in these versions. OpenCV released OpenCV-3.4.4 and OpenCV-4.0.0 on 20th November.
