Tensor multi-view clustering method for natural image segmentation

Abstract

Image segmentation methods based on clustering have become a advancement in the field of computer vision, and the performance of these methods mainly depends on the performance of the clustering algorithm. However, these methods have some shortcomings. First, a single feature cannot accurately obtain the complete information of the superpixels. Second, the commonly used Euclidean distance cannot extract the nonlinear manifold structure between superpixels. Third, the high-dimensional information between superpixels is not considered. Therefore, this article proposes a Tensor Multi-view Clustering Method for Natural Image Segmentation (TMCNIS), in which firstly the multiclass features of the superpixels are extracted to obtain complete information. Secondly, the Jensen–Shannon divergence is used to delineate the relationship between superpixels to obtain a more complete nonlinear structure. Thirdly, an adaptively weighted tensor Schatten-p norm is proposed to better approximate the target rank of the tensor. It also automatically shrinks the singular values appropriately to construct a finer tensor, thus fully capturing the spatial structure in the tensor. Experimental results on four clustering datasets and two image segmentation datasets demonstrate the superiority of TMCNIS compared to existing methods.
