Video Frame Interpolation Implementation Using OBMC (Overlapped Block Motion Compensation)

This content presents a code implementation for video frame interpolation using the OBMC (Overlapped Block Motion Compensation) algorithm. By leveraging existing motion vectors and two adjacent frames (previous and subsequent), the OBMC algorithm computes intermediate interpolated frames through weighted averaging of overlapping block predictions. The implementation typically involves partitioning frames into blocks, estimating motion vectors between reference frames, and applying smooth weighting functions at block boundaries to create seamless transitions. This approach significantly enhances video fluidity and visual quality by reducing blocking artifacts and improving motion continuity, ultimately providing viewers with a superior visual experience. The core algorithm operates by calculating weighted sums of overlapping block predictions where blocks near boundaries contribute less to the final interpolated pixel values, ensuring smooth transitions between motion-compensated blocks.
