Repairing Bad Co-segmentation using Its Quality Evaluation and Segment Propagation

Abstract

In this paper, we improve co-segmentation performance by repairing bad segments based on their quality evaluation and segment propagation. Starting from co-segmentation results of the existing co-segmentation method, we first perform co-segmentation quality evaluation to score each segment. Good segments can be filter out based on the scores. Then, a propagation method is designed to transfer good segments to the rest bad ones so as to repair the bad segmentation. In our method, the quality evaluation is implemented by the measurements of foreground consistency and segment completeness. Two propagation methods such as global propagation and local region propagation are then defined to achieve the more accurate propagation. We verify the proposed method using four state-of-the-arts cosegmentation methods and two public datasets such as ICoseg dataset andMSRC dataset. The experimental results demonstrate the effectiveness of the proposed quality evaluation method. Furthermore, the proposed method can significantly improve the performance of existing methods with larger intersection-overunion score values.

The segmentation results of the proposed method based on [ICCV2011].The results of Hall-red and Cheetah in ICoseg dataset and Signs and Faces in MSRC dataset are displayed. For each block, the original images, the initial segments and our segments are shown from the top row to the bottom row, respectively.
