摘要

在图像处理和机器学习的推动下,植物识别对生态研究和农业管理至关重要。然而,在复杂的背景下,挑战出现了,需要强大的算法来区分目标植物和周围的元素。叶片图像分割是准确分离和分析单个叶片结构,促进精确物种鉴定的关键。本文提出了一种复杂背景下的树叶分割算法。我们的方法以其低计算复杂度而闻名,这使得它非常适合计算资源有限的环境。首先,我们粗略地划分叶子区域,以便定义前景模板。其次,我们通过基于图的显著性处理,根据前景模板对剩余图像区域的相似性进行排序。最后,使用随机森林对得到的对比度图进行细化,以确保最佳的叶/背景分离。实验表明,我们的算法优于几种竞争的分割方法。

Segmentation of plant leaf images in natural scenes by integrating graph diffusion compactness and global refinement
Plant recognition, driven by advancement in image processing and machine learning, is crucial for ecological studies and agricultural management. However, challenges arise in complex backgrounds, requiring robust algorithms to differentiate target plants from surrounding elements. Leaf image segmentation is pivotal in accurately isolating and analyzing individual leaf structure, facilitating precise species identification. In this paper, we propose an algorithm for leaf segmentation in complex backgrounds. Our approach is notable for its low computational complexity making it well-suited for environments with restricted computational resources. First, we delimit roughly leaf areas in order to define the foreground template. Second, we rank the similarity of remaining image regions according to the foreground template through a graph based saliency process. Finally, the obtained contrast map is refined by using random forests to ensure optimal leaf/background separation. Experiments demonstrate that our algorithm outperforms several competing segmentation methods.
