Superpixel Segmentation via Density Peaks

Abstract

Superpixel segmentation, a preprocessing component, is widely used in computer vision tasks. Superpixel algorithm is supposed to generate superpixels with required boundary adherence, compactness as well as less computational complexity. However, most of the existing superpixel algorithms do not perform satisfactorily when it comes to compactness and boundary adherence, as they are a paradox in nature. In this paper, we propose a new superpixel segmentation method based on density peak (DP) clustering and modification of the original DP algorithm. The experimental results have been compared with state-of-the-art methods, both quantitatively and qualitatively, revealing the efficient outcomes that adhere to the object boundaries better than others.
