Descriptor Matchers 2D 特征框架

class   cv::BFMatcher
  Brute-force descriptor matcher. 更多...
class   cv::DescriptorMatcher
  Abstract base class for matching keypoint descriptors. 更多...
class   cv::FlannBasedMatcher
  Flann-based descriptor matcher. 更多...


Matchers of keypoint descriptors in OpenCV have wrappers with a common interface that enables you to easily switch between different algorithms solving the same problem. This section is devoted to matching descriptors that are represented as vectors in a multidimensional space. All objects that implement vector descriptor matchers inherit the DescriptorMatcher 接口。
