J. C. Rubio, J. Serrat, A. Lopez, N. Paragios
2012 2012 IEEE Conference on Computer Vision and Pattern Recognition  
Region matching is applied to exploit inter-image information by establishing correspondences between the common objects that appear in the scene.  ...  Co-segmentation is defined as jointly partitioning multiple images depicting the same or similar object, into foreground and background.  ...  In our third experiment we use the region matching output to identify parts of the common objects co-segmented.  ...

Image Co-skeletonization via Co-segmentation [article]

Koteswar Rao Jerripothula, Jianfei Cai, Jiangbo Lu, Junsong Yuan
2020 arXiv   pre-print
Different from the existing works geared towards co-segmentation or co-localization, in this paper, we explore a new joint processing topic: image co-skeletonization, which is defined as joint skeleton  ...  Therefore, we propose a coupled framework for co-skeletonization and co-segmentation tasks so that they are well informed by each other, and benefit each other synergistically.  ...  However, skeleton pixels usually lie in homogeneous regions (see Fig. 2 (d)&(e)) and are thus challenging to match.  ...
