The aim of this research is to develop model of leaf shape outline drawing from botanical textual description. The B-spline generative shape method (BsGSM) and the leaf shape synthesis system were used in this research. The approach was based on merging tip, side and base shape, plus marginal details. The structure of the system consists of three main parts which were the text processing module, shape template and drawing module. Two expert botanists were referred to assess the drawing result to ensure the result is parallel with a botanical point of view. The findings show that the use of BsGSM produced good result except for some minor visual error. A similar result was also obtained while producing the details of the leaf. The shape template appeared simple and very useful for easier information retrieval. As a conclusion, the BsGSM was practical to model and produce the details of leaf. The developed leaf shape synthesis system facilitates amateur and novice botanists to readily se.....

The aim of this research is to develop a new model of details for the leaf serration before wrapping it onto the overall leaf margin. For this purpose, we used the offset of the original leaf shape outline. The model of the leaf consists of several leaf parts are represented with B-spline curves which also represent the offset. We propose a new algorithm to represent the pattern of the details. The details are applied as an offset to the underlying curve. An algorithm how the pattern combines to the margin was also explained. The results of the drawings are divided into three categories: satisfactory, acceptable, and unsatisfactory. Expert botanist was referred to assess the drawing result to ensure the result is parallel with a botanical point of view. The findings show that the geometry of the details was satisfactory, except for some minor distortion. As the implication, this research allows novice botanists and amateurs to readily see a picture which they might find it hard to visu.....
