Cyclops


Analyze and Track Live Video

Cyclops by Eric Singer (Code Artistry LLC) is a Max object for analyzing and tracking live video in real time.

Through a simple interface, you can track performers and users with a video camera and analyze greyscale and color information from the live image. You can use the resulting Cyclops data to control MIDI, audio, video and anything else that you can do in Max.

Cyclops Applications

  • track dancers or other performers on stage
  • interact with users in interactive installations
  • create video-tracking-based musical instruments and performance interfaces
  • create non-invasive user interfaces

How Cyclops Works

Cyclops receives live video from a QuickTime input source and analyzes each frame of captured video in real-time. It divides the image area into a grid of rectangular zones and analyzes the zones for greyscale, threshold, difference (motion) and color. Cyclops allows you to specify the grid resolution, target zones for analysis and indicate the type of analysis to be performed in each zone. Cyclops outputs messages for each analyzed video frame that can be used to trigger any Max processes or control any patch parameters.
