Unsupervised Cosegmentation based on Global Graph Matching
Takanori Tamanaha, Hideki Nakamaya · 2015
Cosegmentation is defined as the task of segmenting a common object from multiple images. Hitherto, graph matching has been known as a promising approach because of its flexibility in matching deformable objects and regions, and several methods based on this approach have been proposed. However, candidate foregrounds obtained by a local matching algorithm in previous methods tend to include false-positive areas, particularly when visually similar backgrounds (e.g., sky) commonly appear across images.
