| 2015-10-19 20:31:54 -0600 | asked a question | Most efficient format to save and load file Hi all, I'm wondering if YML/XML is the most efficient format to save and load file in OpenCV. The situation is that I'm gonna have a really big SIFT features matrix (say, 10 million features, which means 10 million rows and 128 columns), and I want to load (read from disk) it in the fastest way possible. Slow saving is ok but reading need to be fast. Thanks |
