Video slicing -- a variant of slit scanning in photography -- extracts a scan line from a video frame and successively adds that line to a composite image over time. The composite image becomes a time line, and its visual patterns reflect changes in a particular area of the video stream. We extend the idea of video slicing by allowing users to draw marks on the source video to select areas of interest. These marks, called tears, are used in place of a scan line, and the resulting composite timeline image provides a much richer visualization of the video data.

Video Slicing

Tear-based video slicing allows users to introduce tears into a video scene. These tears are then re-created over the entire video, and constructed into a timeline. The images below illustrate tear-based video-slicing.

Tears are drawn into the scene.
A timeline is drawn for those tears in the video.

Description of Project Activities

Build an interactive application that facilitates the interactive navigation and selection of locations in the video using the timeline.
