The Problem

• Biologists want to study group insect behavior.
• Currently this is done manually, by staring at
  video and taking notes.
• We would like to automate the task of tracking
  insects.

The Problem

• Computer vision programs can perform the
  tracking.
• Setup is too complicated for non-computer
  experts.
• How can we simplify the configuration task?

Biotracking Configurator

• Specifications
• System must allow users to define and manage
  colors for use by a video color tracking program.
• Should allow users to choose color from actual
  videos and images.
• Constant feedback and multiple views should be
  available to assist in finding the 'right' range
  of colors for tracking.
• Actions should be easy to undo.
