different features from same image

April 16, 2021 - 10:09am #1

I was trying to improve the augmentability of an image target  by adding to it a little geometrical shape (a star).

Instead of improving the image, the change made the situation worse.

It seems that adding the star decreases the number of features throughout the image, not just in the area where it was added.

I attached the image target (the labyrint) and the image showing its features, the image with the added star and the image showing its features.

I would be really grateful If anyone can explain to me the reason, thanks

Hi,

In the background we have a system that processes the picture. In general the picture you have chosen is not ideal as it lacks contrast, is repetitive and is not rich in details.

For an optimal experience, I would recommend going over following articles: https://library.vuforia.com/features/images/image-targets/best-practices-for-designing-and-developing-image-based-targets.html

and

Thank you.
