Adaptive Frame Interpolation for Video Motion Accuracy

The patent applies dynamics by making the interpolation approach adaptive rather than static. The system dynamically selects between Lagrangian and Eulerian interpolation methods based on real-time analysis of pixel motion characteristics, motion magnitude, and scene complexity. This dynamic adaptation allows the system to optimize motion estimation accuracy for different video content types while managing computational complexity through selective application of appropriate methods.

The patent changes the parameter of interpolation method selection based on analyzed video characteristics. By evaluating motion magnitude, pixel correspondence quality, and scene complexity, the system adjusts which interpolation approach (Lagrangian or Eulerian) is applied to different regions or frames, thereby improving overall motion estimation accuracy while maintaining manageable computational requirements.

The patent makes the interpolation method dynamic by switching between Lagrangian and Eulerian approaches based on motion magnitude. When pixel displacement is small, Lagrangian interpolation is used for high accuracy. When displacement exceeds thresholds or motion is complex, the system transitions to Eulerian interpolation, which handles large motions more effectively. This dynamic method selection resolves the contradiction between accuracy and adaptability.

The patent introduces an intermediary analysis step that evaluates pixel motion characteristics before selecting the interpolation method. This intermediary assessment of motion magnitude and scene complexity acts as a mediator to determine whether Lagrangian or Eulerian interpolation should be applied, enabling the system to overcome the limitations of each individual method by selecting the appropriate one for each scenario.

The patent applies dynamics by making the interpolation method adaptive to motion characteristics. For small motions where pixel correspondence is critical, the system dynamically selects Lagrangian interpolation to maintain high accuracy. For large motions where displacement exceeds reliable correspondence thresholds, the system transitions to Eulerian interpolation. This dynamic selection resolves the contradiction by matching the method to the motion scenario.

The patent applies local quality by allowing different interpolation methods to be applied to different regions or frames based on local motion characteristics. Rather than using a single global method, the system analyzes local pixel motion and applies Lagrangian interpolation where accuracy is paramount and Eulerian interpolation where large motion occurs, thereby optimizing performance locally across the entire video sequence.

The patent makes the interpolation system dynamic by automatically selecting between Lagrangian and Eulerian methods based on analyzed video characteristics. Rather than requiring manual intervention or complex multi-step processes, the system dynamically adapts the interpolation approach to match scene complexity and motion characteristics, thereby maintaining both operational simplicity and high quality output across diverse video content.

The patent creates a universal interpolation system that can handle multiple types of video content (different scene complexities, motion magnitudes, and frame rates) through a single integrated framework. The system evaluates video characteristics and selects the appropriate interpolation method, providing multi-functional capability that maintains quality across diverse scenarios without requiring separate processing pipelines for different content types.
