I would like to compute the Content Based Image Retrieval but i don't know how i do that.

Thank you.

Best Regards

Efficiency usually means speed, memory use and storage requirement. For storage requirement, you can simply check your hard disk and see how large space is required for storing your data, e.g. features. But you have to write codes to accurately measure speed and memory use.

If you are talking about retrieval accuracy, which is usually known as effectiveness, you need to google by "precision", "recall", "f1-score", "average precision" and "mean average precision". You will find wikipedias and tutorials on how to compute these statistics.
