Poor success rate

August 9, 2021 - 11:57pm #1

I uploaded 10k images and then resubmitted each one as a query to see how many would be properly identified by Vuforia.  I was disappoint to find that it only recognized approx 25% of the identical images!!!  Am I perhaps doing something wrong?  Does recognition get better with bigger images?  Thx

Hey there,

 

Sorry for the delayed response. I don't have anything sadly that I could provide to give you better results other than the documentation I shared before. I also cannot provide you with a test account. I'd recommend starting with a smaller batch of images so that you don't exceed your limit monthly.

I'm also sorry that I cannot be of more help to you.

 

Kind regards,

Hey Patrick,

All of the images are more or less unique.  They are pre-existing images so I don't have much control over the contrast.  The average image size is 45k.

That said, I uploaded some family photos that were between 400 - 999k and my success rate was almost 100%!?  Does that make any sense?

Unfortunately, I've already exceeded my 10k reco limit for the month with 2 tests!   Any chance I can get  test account with more recos for a limited time for testing?

Thx

Dear,



Could you elaborate a little on your findings? How many identical images did you have, and how many were recognized? Larger image files will not help, since they're compressed nonetheless. You should not rely on text and make sure there's enough contrast. There's a lot of information regarding best practices which you can find here:  https://library.vuforia.com/features/images/image-targets/best-practices-for-designing-and-developing-image-based-targets.html
