Annotator

This is a simple tool for annotating (short) videos. It is designed to facilitate frame-level annotations, at the expense of having to load the entire video into memory. Future versions may relax this requirement.

Building

Requirements are:

• libconfuse (for parsing config file)
• opencv (for video playback)

Compile by running:

make

Usage

Available labels are configured in annotator.conf. Controls are as follows:

• Number keys: Make annotation
• c: cycle through rectangle labels
• Escape: Quit (doesn't save)
• Space: Pause
• Left arrow: Go backward 1 frame
• Right arrow: Go forward 1 frame
• Up arrow: Seek backard 1 second
• Down arrow: Seek forward 1 second
• u: Undo
• r: Redo
• Delete: Remove closest annotation to current frame
• s: Save (there is no autosave)
