| Abstract:
A machine vision algorithm for estimating water potential of a tomato canopy was developed. The algorithm extracted lines reflecting inclinations of rachises of tomato plants from the whole canopy image obtained from a fixed position slightly above the canopy. The average incline of the extracted lines correlated well with water potential of tomato plants. This algorithm can be implemented in an automated irrigation system. | |
