Hi @Ramoupixels,

Could you please elaborate on your feedback regarding more pricing for less number of recognitions? After I receive it, I will forward it to the product management team.

Thank you.

I'm  also not happy with more pricing for less number of recognitions

Hello,

his topic is briefly touched on in the following article: https://library.vuforia.com/articles/Solution/How-To-Work-with-Device-Databases.html

Vuforia's recommendation is a maximum of 1000 Image Targets in a single device database. However, there is no hard limit to the number that can be included.

That being said, you should be mindful of the amount of memory and CPU that your application will use when loading a large device databases. Vuforia adds each target in the device database to a dynamic search tree in your app's memory. Dynamic loading and unloading of device databases can be utilized to optimize memory usage (see DataSet APIs below). This technique can also help with CPU utilization during detection and tracking as Vuforia will require additional processing when attempting to detect large numbers of Image Targets in each camera frame. This is especially true for target detection, which is more CPU intensive than tracking.

Here are pointers to the DataSet APIs:
