Once you edit your image to enhance its rating, then you can upload it to create the target;

you can then print the enhanced image to create the target in the "real world".

Hi... Im new in developing AR for a museum where preserve animals!

I confuse about image tracking enhancement if it will be affect in the real world scene because of strong local contrast that will apply to the image to get the high tracking feature or use the edited image to properly track the image?

Sorry for bad english! 

Thanks for replies!

Great. Thank you.

Hi, 

Yes, I've posted it and looking forward for that support on future release of Vuforia.

thanks

What you describe is not supported. But I will pass the message to the product so this may be taken into consideration for future versions of Vuforia.

Meanwhile, you could post this as a "feature request" in our forum wish-list:

Hi, 

I see. So are there any way to allow the user to define some points and  Vuforia engine will take those point to construct camera pose estimation? It's like another type of user defined target.

Thanks 

I see. Well, you would probably need to create a User Defined Target by taking a camera shot of the floor area around the chair;

if you take a picture of the whole room, this is going to be difficult, because the room is three-dimensional, but once you capture it in a picture, it will become just a flat image...

Hi,  consider I want to render a virtual chair on the floor. When I captured the whole room as predefined target, normally I would get the chair was sitting orthogonally with respect to X-Y axis of target reference frame whereas what I want to achieve is that chair's sitting correctly on the floor like this picture below

in this picture, virtual chair sat behind the real one.

Hi, not sure I understand your question: is it just about usuing a target reference frame which is rotated (i.e. different axis direction) with respect to to another one ?
