  1. TEAM Re.PlAYQuality Assurance Michael Andrews SooHyun Jang David Jia Nat Storer

  2. Status Update • Camera and touchscreen arrived! • Functional code for streaming video from camera onto Pandaboard • 5 second rolling buffer • Key press trigger for center point of interpolation • Touchscreen semi-functional • Interpolation code is not aesthetically pleasing (blurred artifacts) • Need code for a GUI for touchscreen interface

  3. Quality Assurance Metrics • Processing Speed • Desirability of product sharply decreases if processing takes too long (approx. >1min) • Measure average interpolation speed against total number of frames to interpolate • Accuracy of Interpolation • Current algorithm runs in real-time but far from ideal quality • Diff pixels between interpolated video frames and original slow motion video frames

  4. Test Plan – Camera Interface • Determine stability of camera SDK and performance of streaming video to Pandaboard • Tests can be automated with a script

  5. Test Plan – Touchscreen • Make sure GUI does not get into unexpected states • Determine fidelity of actual touchscreen interface • Tests must be performed manually

  6. Test Plan – Interpolation • Determine degree of success of interpolation algorithm • There will always be some subjectivity in this • This test will help improve interpolation code • Test can be automated with a script

  7. Test Plan – Wi-Fi • Ensure reliability of Wi-Fi connection and the user’s ability to upload videos to Youtube(stretch goal) • Tests can be automated with a script

  8. Test Plan – Limitations • Find maximum video length for which processing time is acceptable • Determine what types of videos can be slowed down using this product • Balloon popping may be too fast for 120fps to capture enough original frames • Spinning propeller cannot be sampled fast enough to determine direction of rotation (Nyquist Sampling Theorem)

  9. Test Plan – Overall System • Stress test – write script to repeatedly run interpolation code for long periods of time • Ensure users are always notified when errors do occur (i.e. – camera SDK breaks or Wi-Fi becomes unavailable)
