opencv_contrib4.5.0

Build with extra modules​

opencv_contrib 是 opencv 的拓展模块，其中包含了如 DNN 模块等拓展模块

Cmake 选项为 -DOPENCV_EXTRA_MODULES_PATH={path}/opencv_contrib/modules

Generate pkg-config info​

启用 PKGCONFIG 选项将生成 opencv4.pc 文件，便于使用 pkg-config

Cmake 选项为 -DOPENCV_GENERATE_PKGCONFIG=ON

Parallel processing​

一些OpenCV算法可以使用多线程来加速处理

  • Linux 默认后端为pthreads库

Cmake 选项为 -DWITH_PTHREADS_PF=ON

GUI backends (highgui module)​

默认开启 GTK 支持，可以选择开启 QT 支持更高级的GUI操作

Deep learning neural networks inference backends and options (dnn module)​

protobuf 为默认开启

Cmake 选项为 -DWITH_PROTOBUF=ON、-DBUILD_PROTOBUF=ON

TBB

  • 安装依赖 sudo apt-get install libtbb2 libtbb-dev

Cmake 选项为 -DWITH_TBB=ON
