Abstract: Leaf vein is inherent property of plant leaf and a significant feature for plant recognition.Extraction of leaf vein feature is good for automatic leaf recognition.It is difficult because of complicated and diversified characteristic of leaf vein.An approach based on Top-Hat transform is proposed.The direction of each pixel on leaf image is calculated by Gauss gradient.And the Top-Hat transform is carried by multidirectional Top-Hat operators.Finally,leaf vein is extracted by threshold segmentation.Compared with conventional threshold-based methods,experimental results demonstrate that it is capable of extracting more accurate modality of leaf venation for subsequent leaf recognition.

Key words: Top-Hat transform, leaf vein extraction, Gauss gradient, mathematical morphology
