dll文件和jar文件，可以帮助你在java环境下调用opencv4.1.0的相应方法，其中已经加入了opencv_contrib的相关算法，例如SURF算法和SIFT算法。免去了你自己用cmake，vs2017去编译源码的烦恼。

OpenCv controb 4.0.0，因为从github上下载有限制，这里上传方便你我他

编译好的opencv3.2 含contrib模块 QT windows系统可用

opencv_contrib_python-3.4.0.12-cp36-cp36m-win_amd64.whl 是windows系统opencv的python版本，支持python3.6，可在命令行直接安装。

VS2015编译的OpenCV4.5.3源代码生成的win32平台与x64平台动态库开发包，包含了contrib模块。编译时勾选了nonfree，同时也编译了freetype模块，可以在图片上输出utf-8编码的中文。

opencv3.4.5的源码，包括opencv3.4.5-contrib，不过编译时下载较为麻烦

opencv_contrib-3.4.10重新下载所需要的文件打包，包含的文件有opencv_contrib-3.4.10，opencv3.4.10，cmake-3.14.7-win64-x64.msi，以及boostdesc_bgm.i等i文件

opencv-contrib-python-3.4.1.15.whl 包含支持SIFT！！！下载文中链接， pip install opencv-contrib-python-3.4.1.15。找了一上午， 终于在这里发现：https://pypi.tuna.tsinghua.edu.cn/simple/opencv-contrib-python/

opencv3.4.0在vs2015下的32位库，库已经生成了contrib模块，并提供html格式文档
