摘要:

粒子竞争与合作(PCC)是一种基于图的半监督学习方法。当PCC应用于交互式图像分割任务时,像素被转换为网络节点,并且每个节点根据从图像中提取的一组特征之间的距离连接到其k-最近邻居。构建适当的网络来馈送PCC对于实现良好的分割结果至关重要。然而,取决于要分割的图像的特性,某些特征对于识别片段可能比其他特征更重要。本文提出了一种评价候选网络的指标。因此,建立网络成为一个问题,优化一些特征权重的基础上提出的索引。对Microsoft GrabCut数据库中的真实图像进行了计算机模拟,实验结果表明了该方法的有效性。

英文摘要:

Particle competition and cooperation (PCC) is a graph-based semi-supervised learning approach. When PCC is applied to interactive image segmentation tasks, pixels are converted into network nodes, and each node is connected to its k-nearest neighbors, according to the distance between a set of features extracted from the image. Building a proper network to feed PCC is crucial to achieve good segmentation results. However, some features may be more important than others to identify the segments, depending on the characteristics of the image to be segmented. In this paper, an index to evaluate candidate networks is proposed. Thus, building the network becomes a problem of optimizing some feature weights based on the proposed index. Computer simulations are performed on some real-world images from the Microsoft GrabCut database, and the segmentation results related in this paper show the effectiveness of the proposed method.
