摘要:

图像分析技术为基于种子形态和颜色特征的维管植物分类提供了新的工具,在系统研究方面做出了重要贡献。然而,为了提取形态和色度特征,有必要分割包含待分析样品的图像。这个阶段代表了图像处理中最具挑战性的步骤之一,因为很难从背景中分离均匀和同质的对象。在本文中,我们提出了一个新的,开源插件的种子样本的图像的自动分割。这个插件是用Java编写的,允许它与ImageJ开源软件一起工作。新插件在来自120种豆科植物的3,386个种子样本上进行了测试。使用平板扫描仪获取数字图像。为了测试这种方法在识别物体边缘并将其与背景分离方面的有效性,每个样本都使用四种不同的蓝色背景进行扫描,总共制作了480张数字图像。将新插件的性能与使用相同种子样本的基于双重图像采集(具有黑白背景)的方法进行比较,其中使用Core ImageJ插件手动分割图像。结果表明,新插件能够分割所有的数字图像,而不会产生任何目标检测错误。此外,新插件能够在平均0.02秒内分割图像,而手动方法的平均执行时间为63秒。这个新的开源插件被证明能够处理单个图像,并且在处理大量图像和各种形状时,在时间和分割方面非常高效。

英文摘要:

Image Analysis offers a new tool for classifying vascular plant species based on the morphological and colorimetric features of the seeds, and has made significant contributions in systematic studies. However, in order to extract the morphological and colorimetric features, it is necessary to segment the image containing the samples to be analysed. This stage represents one of the most challenging steps in image processing, as it is difficult to separate uniform and homogeneous objects from the background. In this paper, we present a new, open source plugin for the automatic segmentation of an image of a seed sample. This plugin was written in Java to allow it to work with ImageJ open source software. The new plugin was tested on a total of 3,386 seed samples from 120 species belonging to the Fabaceae family. Digital images were acquired using a flatbed scanner. In order to test the efficacy of this approach in terms of identifying the edges of objects and separating them from the background, each sample was scanned using four different hues of blue for the background, and a total of 480 digital images were elaborated. The performance of the new plugin was compared with a method based on double image acquisition (with a black and white background) using the same seed samples, in which images were manually segmented using the Core ImageJ plugin. The results showed that the new plugin was able to segment all of the digital images without generating any object detection errors. In addition, the new plugin was able to segment images within an average of 0.02 s, while the average time for execution with the manual method was 63 s. This new open source plugin is proven to be able to work on a single image, and to be highly efficient in terms of time and segmentation when working with large numbers of images and a wide diversity of shapes.
