Algorithmic Tuning - Motion and Alignment
This post describes further enhancement and tuning of the 2D to 3D algorithm to further reduce risk of discomfort. The latest enhancements include:
- 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.
I have again used the "Avatar: The Way of Water" trailer in these examples:
