Image analysis is driving a renaissance in growth measurement

► Digital image capture/analysis is reviving the art and science of measuring growth. ► Object boundaries and midlines are the key morphological features to track. ► Most growth studies have been based on time series of 2D images but 3D is possible. ► Tracking image patches within an object generates a kinematic description of growth. ► Automation of acquisition and analysis creates the throughput needed for phenotyping.
