摘 要: 针对植物叶脉复杂多变导致叶脉信息提取困难的问题,提出在HSI颜色空间中提取叶脉信息的方法。该方法根据植物叶图像在HSI颜色空间中色度H的分布,把植物叶分为单色叶和对比色叶两类;然后利用色度分量H提取对比色叶的叶脉信息,对于单色叶则采用色度分量H和亮度分量I特征融合的方法提取。实验结果证明,该方法能有效提取各种类型的叶脉信息,为下一步植物叶的识别打下良好的基础。 Extraction of leaf vein is difficult because of complicated and diversified characteristic of vein.It was proposed that vein information was extracted in HSI space.Firstly,leaf was divided into concolorous and contrasting color leaf according to distribution of hue.Secondly,vein of contrasting color leaf can be extracted using only hue information.But for the concolorous leaf,fusion of hue and intensity information was used.Experiment results show that the proposed method can extract leaf vein effectively for subsequent leaf recognition.
