摘要:

超像素算法将具有相似颜色和其他低级别属性的像素分组,越来越多地用于图像分割的预处理。近年来,一个焦点已经放在发展几何超像素的方法,促进几何图像特征的提取和分析。基于图的超像素方法在几何方法中是重要的,因为它们生成紧凑且稀疏可表示的超像素。将广义平衡功率图引入到超像素领域,提出了一种称为Power-SLIC的图方法。Power-SLIC是第一个生成分段二次边界的几何超像素方法。它的速度,竞争力的快速国家的最先进的方法,是前所未有的图表方法。大量的计算实验表明,Power-SLIC算法在边界召回率、分割误差、可达到的分割精度和压缩质量等方面均优于现有的图方法。此外,Power-SLIC对高斯噪声具有鲁棒性。

英文摘要:

Superpixel algorithms grouping pixels with similar color and other low-level properties are increasingly used for pre-processing in image segmentation. In recent years, a focus has been placed on developing geometric superpixel methods that facilitate the extraction and analysis of geometric image features. Diagram-based superpixel methods are important among the geometric methods as they generate compact and sparsely representable superpixels. Introducing generalized balanced power diagrams to the field of superpixels, we propose a diagram method called Power-SLIC. Power-SLIC is the first geometric superpixel method to generate piecewise quadratic boundaries. Its speed, competitive with fast state-of-the-art methods, is unprecedented for diagram approaches. Extensive computational experiments show that Power-SLIC outperforms existing diagram approaches in boundary recall, under segmentation error, achievable segmentation accuracy, and compression quality. Moreover, Power-SLIC is robust to Gaussian noise.
