A Tablet Annotation Tool for Endoscopic Videos

We present a tool for mobile browsing and annotation tailored for endoscopic videos. Professional users can utilize this tablet app for patients debriefings or educational purposes. It supports text input, free-hand and shape drawing as well as angle measurements, e.g. for comparing instrument orientation. It is possible to annotate single frames as well as user-defined video sections. Moreover, it provides easy and efficient navigation via a zoom-able navigation bar that is based on frame stripes. Frame stripes are created by extracting a single, one pixel wide vertical stripe from every keyframe. The stripes are then arranged next to each other to form a uniform bar. This gives users great overview of the content of a given video. Furthermore, the app supports creation of custom reports based on the entered annotations that can be directly mailed or printed for further usage.
