Before the availability of digital photography resulting from the invention of charged couple devices in 1969, the measurement of plant architecture was a manual process either on the plant itself or on traditional photographs. The introduction of cheap digital imaging devices for the consumer market enabled the wide use of digital images to capture the shape of plant networks such as roots, tr...

Based on our previous work in deformable shape modelbased object detection, a new method is proposed that uses index trees for organizing shape features to support contentbased retrieval applications. In the proposed strategy, different shape feature sets can be used in index trees constructed for object detection and shape similarity comparison respectively. There is a direct correspondence be...

This article proposes an animating system for plant growth in the Lindenmayer (L) system in which alphabets are parameterized to the length, size, and position of each component of the plant. The growth rate is approximated by sigmoidal curves. To achieve a realistic leaf shape, a set of shape functions is used to transform a skeleton of primary branches into the final shape. Genetic algorithm ...
