core a compact module defining basic data structures, including the dense multi-dimensional array Mat and basic functions used by all other modules.

定义基础数据结构，包括Mat和其他模块的基本函数

imgproc an image processing module that includes linear and non-linear image filtering, geometrical image transformations (resize, affine and perspective warping, generic table-based remapping), color space conversion, histograms, and so on.

图像处理模块包括线性和非线性图像滤波，图像几何变换，颜色空间变换，直方图等

video a video analysis module that includes motion estimation, background subtraction, and object tracking algorithms.

视频分析模块包括运动估计、背景差分、运动跟踪算法

calib3d basic multiple-view geometry algorithms, single and stereo camera calibration, object pose estimation, stereo correspondence algorithms, and elements of 3D reconstruction.

基本的多视角几何算法，单、双相机标定，物体位姿估计，立体相似性算法，三维重建

features2d salient feature detectors, descriptors, and descriptor matchers.
