We have used Vuforia on a couple different platforms, chasing the best accuracy. The question has come up multiple times "what resolution is Vuforia actually processing on". I thought I saw somewhere that 640x480 was what was used, despite a HD webcam. But I'm hoping someone can help answer this definitively based on specific Vuforia support for different platforms.
Could someone fill in / respond with the resolution that Vuforia uses / accesses from different cameras on these systems for simple 2D object tracking?
2) Samsung S6:
3) Samsung S6 using Gear:
4) "Stock" USB webcam (assume a HD USB webcam using Windows drivers):
This would be very useful. Sorry in advance if there is already some post / answer like this, but I couldn't find it...
