I'm trying to enhance the detection results of vuforia on a windows tablet at a greater distance from the markers.
Therefore I tried to increase the resolution of the webcam profiles, which works as expected but obviously comes with a significant performance drop.
To use the same level of detail without losing so much performance I think it would be great to have the option to define vertical and horizontal borders on the captured imagestream.
As mentioned here: https://developer.vuforia.com/forum/android/crop-camera-image it is possible in c++ to pass a cropped image to the vuforia detector.
Is this also possible for the unity integration?
If not, is it possible to expose the tracker method that takes the camera image and handle the imagecapturing by myself?
