Load

Load(filename, storage=NULL, name=NULL) → generic

Loads an object from a file.

Parameters:

• filename (str) – File name
• storage (CvMemStorage) – Memory storage for dynamic structures, such as CvSeq or CvGraph . It is not used for matrices or images.
• name (str) – Optional object name. If it is NULL, the first top-level object in the storage will be loaded.

The function loads an object from a file. It provides a simple interface to Read . After the object is loaded, the file storage is closed and all the temporary buffers are deleted. Thus, to load a dynamic structure, such as a sequence, contour, or graph, one should pass a valid memory storage destination to the function.
