  1. ViPERVideo Annotation and Performance Evaluation viper-toolkit.sf.net

  2. The ViPER Toolkit • Unified video performance evaluation resource, including: • ViPER-GT – a Java toolkit for marking up videos with truth data. • ViPER-PE – a command line tool for comparing truth data to result data. • A set of scripts for running several sets of results with different options and generating graphs.

  4. ViPERGround Truth Editing viper-toolkit.sf.net

  5. Ground Truth Editing

  6. Ground Truth Editing • Lets the user specify the task and the interpretation. • Improved (Verson 4) • Schema editor. • Timeline view. • Supports undo/redo. • All new video annotation widget. • MPEG-2 support on Windows.

  7. Latest Version in Series

  8. Time Line View • Provides summary and editing of annotation. • Very useful for tracking annotation, great for event or activity annotation.

  9. Time Line View • Provides summary of ground truth. • Direct manipulation. • Quick editing of activities, events, and other descriptors. • Some ability to modify descriptors with dynamic attributes directly, if not the attribute values. • Feedback for indirect manipulation. • Easier to notice massive changes.

  10. Play When Valid Feature • New feature divides movie into ‘valid’ segments. • Useful for dividing movie and for playback. • Combined with ‘Generate I-Frame Descriptor’ plug-in, supports i-frame-only mark-up.

  11. Enhanced Keyboard Editing • Support for real-time mark-up of events and activities. • Keys for creating and deleting activities. • Keys for controlling rate of display (jog dials). • Enhance mark-up of spatial data. • Keys for creating, editing of a single descriptor's attribute. • Overall attempt to minimize effort in a GOMS model. • Mouse events unnecessary except for polygon editing.

  12. Video Frame View Enhancements • Display with Respect To • Play back the movie with a spatial object remaining static and the video frame shifting behind it. • Good for editing several things that move together. • Enhanced editing: • More direct manipulation controls. • Zooming enhancements, including zoom history, scroll-wheel-zoom, and center-click-panning.
