最近在学习验证码图片识别，安装完pip install opencv-python之后，发现导入的方法命令有底纹。
解决方案如下：
找到安装python的路径，安装完opencv-python后，在site-packages下会有cv2的文件夹，
将cv2文件夹下后缀名pyd的文件复制到site-packages下，复制复制复制哦。如下图
就没有那样的底纹颜色了。

Introduce option to generate Java code with finalize() or Cleaners interface #28159
Closes https://github.com/opencv/opencv/issues/22260
Replaces https://github.com/opencv/opencv/pull/23467
The PR introduce configuration option to generate Java code with Cleaner interface for Java 9+ and old-fashion finalize() method for old Java and Android. Mat class and derivatives are manually written. The PR introduce 2 base classes for it depending on the generator configuration.
Pros:
1. No need to implement complex and error prone cleaner on library side.
2. No new CMake templates, easier to modify code in IDE.
Cons:
1. More generator branches and different code for modern desktop and Android.
TODO:
- [x] Add Java version check to cmake
- [x] Use Cleaners for ANDROID API 33+
