Computer Vision with OpenCV 3 and Qt5

Summary

Feature detection, description, and matching are probably some of the most important and hot topics in computer vision that are still in intensive progress and improvement. The algorithms that were presented in this chapter are but a fraction of the existing algorithms in the world, and the reason that we chose to present them is the fact that they are all more or less free to use by the public, and also the fact that they are included in OpenCV by default, under the feature2d module. If you are interested in learning about more algorithms, you can also check out Extra 2D Features Framework (xfeature2d), which contains non-free algorithms such as SURF and SIFT, or other algorithms still in experimental states. Of course, you need ...
