Find Similar

I've been thinking in a new feature for "find similar". One of the things I always do before upload something, is check if the same pic is not already in danbooru. However I find sometimes that the "find similar" function not always gives the right answer. I know that this function is not perfect, and sometimes one found your pic within the ones in "more results" and in some cases in "give me more!". Even so, I've found that pics that are flipped horizontaly or vertically are more likely to be considered "unique".
Therefore, I ask and suggest the next thing:

Is there a way to add something like "try horizontal flip" (for images like post #467979 post #320394) and "try vertical flip" (for cases like post #373829 post #352648)? And maybe something like "rotate image 90° to the left or right"?

Maybe I'm asking to much but I really think this would be useful.

Contact: piespy in #iqdb@irc.rizon.net or mail me on Danbooru.

Would probably be better if you contact the author directly.

Also, I fully support this new feature.

To simply check all combinations of rotations and flips, it would make the database check take eight times as long though.

Maybe there's a smarter way of doing this; it should be possible to transform the wavelet coefficients directly and combine the queries. I've tried doing this before though but I don't really understand how the wavelet transformation works, so I never got anywhere with it.

I suppose for now I could add a checkbox to just transform the image and query the database eight times.
