ABSTRACT

In this paper, we propose a novel automatic algorithm for foreground/background labeling. We aim to generate ROI cutout automatically for further processing such as image editing, classification and information retrieval. Different from traditional semi-supervised segmentation method, we use a rather weak prior on boundary label. Accordingly, a global cost function is proposed to combine our prior knowledge with pixel-level feature. We compute fuzzy matting components as building blocks to construct semantically meaningful mattes. Finally, these mattes are hierarchically clustered and ranked by central preference. Experimental results on a large benchmark data set demonstrate the performance of our algorithm.
