Mucus flow visualization
July 10, 2009
David Borland developed a flow visualization technique and used the output of Brian Eastwood’s ImageTracker program to construct this visualization of cilia-driven mucus flow on a human lung cell culture video from David Hill. He overlaid the flow on the cell background determined by ImageTracker.
Flow speed is encoded both by color (blue lowest, through gray to red). Flow direction is along the lines and in the direction pointed to by the arrows.
