GROW MAP-leaf: Digital Image Sequence Processing Setup for monitoring of leaf growth via digital image sequence processing
Data Acquisition
- fixation of a leaf in a plane parallel to camera
- illumination with near infrared-diodes
- image sequence at high frequency in near infrared throughout day and night
Image analysis
- optical flow analysis of image sequence resulting in velocity vector fields
- calculation of divergence to obtain growth maps
Results (example)
Spatial and temporal distribution of leaf growth in 4 species ilustrating typical growth patterns
