摘要

超像素分割算法广泛应用于计算机视觉的预处理步骤中。超像素分割的一个关键方面是保持结构边界。然而,在许多结构复杂的图像中,前景和背景之间的对比度非常低,这成为超像素分割的挑战。本文提出了一种评估灰度图像局部亮度和暗度的新方法。然后利用局部亮度和暗度信息增强弱结构边界进行超像素分割。此外,我们还引入了一种用于SLIC的超像素合并方法,以消除多个超像素块,特别是在不同目标之间的边界附近。实验结果表明,该算法能使超像素更好地贴合目标边界,改善过分割问题。

Multi-Iterative Superpixel Segmentation based on Local Brightness and Darkness Information
Super-pixel segmentation algorithms are widely used in the preprocessing steps for computer vision applications. A crucial aspect of Super-pixel segmentation is preserving structure boundaries. However, in many images with complex structures, the contrast between foreground and background are very low, which becomes a challenge for Super-pixel segmentation. In this paper, we introduce a new method to evaluate local brightness and darkness for gray images. Then, we use local brightness and darkness information to enhance the weak structure boundary for Super-pixel segmentation. Furthermore, we also introduce a Super-pixel merging method for SLIC to eliminate numbers of Super-pixel blocks, especially nearby the boundaries between different objects. The experimental results show the proposed algorithm makes Super-pixels adhere to object boundaries better and improve the over-segmentation.
