ABSTRACT
Co-segmentation addresses the problem of simultaneously extracting the common targets appeared in multiple images. Multiple common targets involved object co-segmentation problem, which is very common in reality, has been a new research hotspot recently. In this paper, an unsupervised object co-segmentation method for indefinite number of common targets is proposed. This method overcomes the inherent limitation of traditional proposal selection-based methods for multiple common targets involved images while retaining their original advantages for objects extracting. For each image, the proposed multi-search strategy extracts each target individually and an adaptive decision criterion is raised to give each candidate a reliable judgment automatically, i.e., target or non-target. The comparison experiments conducted on public data sets iCoseg, MSRC, and a more challenging data set Coseg-INCT demonstrate the superior performance of the proposed method.
