The spatial arrangement of the brightness values of remotely sensed imagery bears important information for forest canopy structures. This paper presents an algorithm to estimate tree crown size and position from color orthophoto images acquired at several seasons. The seasonal change in color of leaves gives us a piece of useful information about the boundary of neighboring tree crowns. The usefulness of the algorithm for practical applications is demonstrated with an experiment on multiple orthophoto images of the northern part of Kyushu Island.
