status update
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
quality assurance metrics
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
test plan camera interface
Test Plan – Camera Interface
  • Determine stability of camera SDK and performance of streaming video to Pandaboard
  • Tests can be automated with a script
test plan touchscreen
Test Plan – Touchscreen
  • Make sure GUI does not get into unexpected states
  • Determine fidelity of actual touchscreen interface
  • Tests must be performed manually
test plan interpolation
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
test plan wi fi
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
test plan limitations
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)
test plan overall system
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)
