f f+1 f + n f K.Uehara, M.Amano, Y.Ariki (Kobe University) and M.Kumano (Ryukoku University) Research Purpose A lot of videos are left behind without editing. • No knowledge of how to edit videosVideo editing support system (ICPR02) • Few useful shots in videos for editing Video navigation system (this paper) Video Shooting Navigation System by Real-Time Useful Shot Discrimination Based on Video Grammar Navigation System Too fast right-pan Slow right-pan Fixed camerawork Score is 80 Pan is fast. Video Grammar Shift R1: Fixed shot durations is longer than 3 seconds. R2: Pan and zoom shots are sur- rounded by fixed shots with about 1 second. R3: Shots with hand-shaking and rapid movement are excluded. R4: Too dark or too bright shots are excluded.
