VTK/Geovis vision toolkit

Requirements

There are two parts to the project:

• Video / related meta data rendering and interactions.
• Displaying video / meta data in geospatial context.

As per our discussion we have gathered following requirements for the project.

• Easy to put together.
• Provides 2D and 3D mode where in 2D it will allow quick validation, manipulation abilities.
• Provides the ability to visualize, video, track, and associated ranking.
• Ability to provide input as sequence of images or a video file.
• Provides the ability to manipulate track data. User should be able to insert a new one, modify the existing one.
• Provides the ability to select a region with pixel level accuracy and draw a track on top of it.
• Provides the ability to play many video files (small or large video) files.
• Provides a layout for the videos in space so that each can be seen clearly for a view point.
• Allows the videos to play individually or globally.1
• Provides the ability to toggle different layers of information.
• Provides geo spatial context.
