Motion Stabilisation of Left and Right Eye Views
Example Frame Showing Motion Compensation for Right Eye View Compared to Left (Scaled Down)

This post describes a significant enhancement to the 2D to 3D algorithm in order to further reduce risk of discomfort. This enhancement includes:

  • Introduction of a new element that performs full frame motion compensation on the right eye view so that it always aligns precisely with the left eye view.
  • Increase in the default frame stretch factor from 5% to 8%, to adjust for the increased precision in frame alignment from the new motion compensation step.
  • Reduction of the default threshold at which the algorithm rejects a frame for 2D to 3D processing, as the result of too much frame to frame motion, from about 20% to 10% of the frame.

Examples:

I have again used the "Avatar: The Way of Water" trailer in these examples:
