It is a visual correspondence estimate, not a complete 3D motion solution.
Jin Dive
Classic optical flow often assumes brightness constancy and spatial smoothness. RAFT uses feature correlations across image pairs and a recurrent update operator to refine dense flow. Occlusion, illumination change, motion boundaries, textureless areas, and large displacement can make correspondence difficult. A flow vector is image-plane motion and does not by itself provide metric depth or object identity. In frame interpolation, estimated optical flow can guide synthesis of intermediate frames between two observed frames; this application depends on the quality of the motion estimate. An occlusion occurs when a scene point is hidden in one frame or newly revealed in another, leaving no valid pixel correspondence in the hidden frame. Flow can therefore be uncertain at occlusion boundaries.
Real-World imuse
Estimate motion between adjacent frames for video analysis.
Inspect flow failures near occlusions or textureless regions.
Use RAFT as a learned model and evaluate it on the intended footage.
Compare flow fields at the camera and object level only when those signals are separated.
Ojo iwaju ti ṣiṣan Optical
Flow remains useful for motion estimation and video processing, often alongside depth, segmentation, or tracking. Evaluate on relevant conditions instead of assuming the model anticipates future motion or resolves occlusion completely.

What is Optical Flow?
Optical flow estimates apparent motion between image frames, often as a displacement vector field. It is a visual correspondence estimate, not a complete 3D motion solution.

Which method uses a 4D correlation volume and recurrent updates for optical flow?
RAFT builds all-pairs correlations and iteratively updates flow estimates.
Why can classic optical-flow assumptions fail in fast motion?
Classic methods rely on simplifying assumptions that can break under large or ambiguous motion.
