Cloud Reco: Image of frame marker got recognized as frame marker

May 27, 2015 - 1:58pm #1

Hi

There is a usecase when Cloud Reco is necessary (due to the large number of targets.)

The targets looks like customized Frame Markers but the intention is to recognize them as DIFFERENT IMAGES as they have distinctive features.

However there is an issue when testing on devices,

  - For Android devices, tried multiple models and it worked

  - However, when using iPhone6, targets with identical "frame" got recognized as the "same image" though the "ID Areas" of the images are different. It seems that those image targets got recognized at Cloud server as Frame markers

 

Can you clarify:

1. For Cloud Reco, will the attached targets be generally treated as Frame markers?

2. What can possibly be the reasons for the difference bet. Android devices and iPhone6

 

Thank you.

Thank you!

Actually we want those pictures to be treated as Image Targets, not Frame Makrers.

Occulusion is a good point. So for this type of Image Target (sharing similar frame),  the Cloud Reco is not reliable, as it may terminate early and get wrong results when the reco engine only relies on the features in the outer frame part?

Frame Markers are limited to 512 markers and don't use a Device DB or Cloud DB. Cloud DB only handles ImageTargets. If you are using CloudReco and uploaded those images to a DB, then they are handled as Image Targets and not Frame Markers. Image Targets can be recognized even when they are partially occluded and so the identical borders in those two images could lead to unexpected recognitions if it doesn't see the unique parts. Frame Markers on the other hand require the entire border of dots to be visible in order to be tracked.
