Hi all,
Sorry to disturb you.
Currently I want to redefine the memory allocator in OpenCV. However I found that the cvSetMemoryManager() function is useless. The source code of it is:
void cvSetMemoryManager(CvAllocFunc, CvFreeFunc, void *)
{
CV_Error( -1, "Custom memory allocator is not supported" );
}
Is there another way to redefine the memory allocator in OpenCV ?
Thank you.
I guess the function says it all. Custom memory allocator is not supported by OpenCV. If you want to use a custom memory allocator, you will have to write overload functions and add own functionality to openCV, then build the whole library yourself. If you do so however, please create a pull request to add this functionality to the library.
Yes, you can redefine cv::Mat allocator !!!
Simple inherent from MatAllocator
Implement the virtual functions needed
Create a singleton instance for your allocator
Pass it to:
Mat::setDefaultAllocator()
worked for me
