Query: On the Issues of TrueDepth Sensor Data for Computer Vision Tasks Across
  Different iPad Generations   In 2017 Apple introduced the TrueDepth sensor with the iPhone X release.
Although its primary use case is biometric face recognition, the exploitation
of accurate depth data for other computer vision tasks like segmentation,
portrait image generation and metric 3D reconstruction seems natural and lead
to the development of various applications. In this report, we investigate the
reliability of TrueDepth data - accessed through two different APIs - on
various devices including different iPhone and iPad generations and reveal two
different and significant issues on all tested iPads.
