摘要

气孔是一种特殊的孔隙,在气体交换和光合作用中发挥着重要作用。显微图像通常用于评估植物气孔的特征,但这可能是一项具有挑战性的任务。通过使用 Matterport 的 Mask R-CNN 实现作为基础模型,对 810 张 Hedyotis corymbosa 叶子表面的显微图像数据集进行了微调,以实现气孔的自动检测。结果令人欣喜,该模型在检测和分割方面的收敛平均精度(mAP)达到了 98%。训练损失和验证损失值分别趋近于 0.18 和 0.37。回归分析表明,预测参数具有统计学意义(p 值小于 0.05)。值得注意的是,在气孔孔面积测量中观察到了最紧密的数据点群,其次是宽度和长度。这凸显了气孔面积在描述气孔特征方面的精确性。尽管原始数据集的低分辨率图像以及灰尘、气泡和模糊等人为因素带来了挑战,但我们创新性地使用了 Mask R-CNN 算法,取得了值得称赞的成果。这项研究为气孔表型分析引入了一种稳健的方法,可广泛应用于植物生物学和环境研究。

New dimension in leaf stomatal behavior analysis: a robust method with machine learning approach

Stomata are specialized pores that play a vital role in gas exchange and photosynthesis. Microscopic images are often used to assess stomatal characteristics in plants; however, this can be a challenging task. By utilizing Matterport’s Mask R-CNN implementation as the foundational model, fine-tuning was conducted on a dataset of 810 microscopic images of Hedyotis corymbosa leaves’ surfaces for automated stomatal pores detection. The outcomes were promising, with the model achieving a convergence of 98% mean average precision (mAP) for both detection and segmentation. The training loss and validation loss values converged around 0.18 and 0.37, respectively. Regression analyses demonstrated the statistical significance (p values ≤ 0.05) of predictor parameters. Notably, the tightest cluster of data points was observed in stomata pore area measurements, followed by width and length. This highlights the precision of the stomatal pore area in characterizing stomatal traits. Despite challenges posed by the original dataset’s low-resolution images and artifacts like dust, bubbles, and blurriness, our innovative utilization of the Mask R-CNN algorithm yielded commendable outcomes. This research introduces a robust approach for stomatal phenotyping with broad applications in plant biology and environmental studies.
