Overview of architectures

CAIN

• PixelShuffle
• Channel attention
• No optical flow computation module

RIFE

• IFNet for approximation of intermediate optical flows
• RefineNet for final refinement

XVFI

The XVFI-Net is based on a recursive multi-scale shared structure that consists of two cascaded modules for bidirectional optical flow learning between two input frames (BiOF-I) and for bidirectional optical flow learning from target to input frames (BiOF-T).

Frame Averaging

A simple weigted sum of two adjucent frames with different coefficients.

Frame Repeating

The left frame in each pair of neighbors was taken and repeated N times.
