python中的OpenCV3中的CreateMemStorage()等价于什么? [英] What is the equivalent of CreateMemStorage() in OpenCV3 in python?

问题描述

我正在从opencv 2.4引用代码，并尝试迁移到opencv 3.1.我找不到完整的迁移指南.

I am referring code from opencv 2.4 and trying to migrate to opencv 3.1. I could not find a complete migration guideline.

推荐答案

CreateMemStorage, as well as many other function to manage dynamic C structures, are now obsolete. This was still present in OpenCV 2.4.12, but is removed in OpenCV 3.

他们指的是C api，它在5年前就被放弃了. 现在，您应该使用C ++ API.根据 OpenCV文档:

They refer to C api, which was abandoned something like 5 years ago. Now you should use C++ api. As reported from the OpenCV doc:

[CreateMemStorage和类似的功能来自] OpenCV 1.x API，用于创建可增长的序列和在CvMemStorage中分配的其他动态数据结构.如果您使用新的C ++， Python ，Java等接口，则不太可能需要此功能.使用std :: vector或其他高级数据结构.

[CreateMemStorage and similar functions are from] OpenCV 1.x API for creating growable sequences and other dynamic data structures allocated in CvMemStorage. If you use the new C++, Python, Java etc interface, you will unlikely need this functionality. Use std::vector or other high-level data structures.

OpenCV提供了过渡指南可能会有所帮助.

OpenCV provides a transition guide that can be helpful.
