Difference between using VDict and dict?

Asked by Raymond

Sorry if this is a newbie question, but the documentation was a little unclear to me. What exactly is the advantage of using a VDict over a regular dictionary. Currently I'm using dictionaries with image filepath as a string for values. What would be different if I used VDict?

In a VDict, the keys are images and there are some methods, that look for a matching key using the image find features.

so if you say (supposing vd is a VDict containing some entries):

val = vd["path-to-an-image"]

you will get the value of the entry, that matches best to the given key image represented by "path-to-an-image".

Your question:
A dictionary with the image path's as keys finds an entry by matching strings. A VDict finds entries by matching images.
In your case, you would have the risk, that you do not get the entry you are looking for, because a similar entry is found with a higher score.

Can you help with this problem?
