초록

Panning and tracking shots are popular photography techniques in which the camera tracks a moving object and keeps it at the same position, resulting in an image where the moving foreground is sharp but the background is blurred accordingly, creating an artistic illustration of the foreground motion. Such shots however are hard to capture even for professionals, especially when the foreground motion is complex (e.g., non-linear motion trajectories). In this work we propose a system to generate realistic, 3D-aware tracking shots from consumer videos. We show how computer vision techniques such as segmentation and structure-from-motion can be used to lower the barrier and help novice users create high quality tracking shots that are physically plausible. We also introduce a pseudo 3D approach for relative depth estimation to avoid expensive 3D reconstruction for improved robustness and a wider application range. We validate our system through extensive quantitative and qualitative evaluations.
