Analysis of the nature of the problem
Video flickering originates from the misalignment of inter-frame features, CanonSwap realizes 97.8% timing coherence through triple technology guarantee (thesis actual measurement data).
Specific Optimization Options
- motion information anchoring: Establish a correlation matrix of motion parameters between frames to ensure continuous transition of data such as head rotation angle.
- Normative spatial normalization: All frames are processed in a uniform standard space, eliminating feature drift due to changes in shooting angle
- optical current assisted compensation: Interpolation compensation for high-frequency motions such as eye blinks and mouth twitches using optical flow estimation
Implementation Considerations
It is recommended that the developer: 1) Check the frame rate stability of the target video 2) Enable light normalization preprocessing for low-light clips 3) Set a pose shift tolerance threshold of 0.3-0.5. Tests show that this method reduces the jitter index (DSI) by 83%
