英文摘要 | A weakly supervised semantic segmentation (WSSS) method aims to learn a segmentation model from weak (image-level) as opposed to strong (pixel-level) labels. By avoiding the tedious pixel-level annotation process, it can exploit the unlimited supply of user-tagged images from media-sharing sites such as Flickr for large scale applications. However, these 'free' tags/labels are often noisy and few existing works address the problem of learning with both weak and noisy labels. In this work, we cast the WSSS problem into a label noise reduction problem. Specifically, after segmenting each image into a set of superpixels, the weak and potentially noisy image-level labels are propagated to the superpixel level resulting in highly noisy labels; the key to semantic segmentation is thus to identify and correct the superpixel noisy labels. To this end, a novel L-1-optimisation based sparse learning model is formulated to directly and explicitly detect noisy labels. To solve the L-1-optimisation problem, we further develop an efficient learning algorithm by introducing an intermediate labelling variable. Extensive experiments on three benchmark datasets show that our method yields stateof-the-art results given noise-free labels, whilst significantly outperforming the existing methods when the weak labels are also noisy.; National Natural Science Foundation of China [61573363, 61573026]; 973 Program of China [2014CB340403, 2015CB352502]; Fundamental Research Funds for the Central Universities; Research Funds of Renmin University of China [15XNLQ01]; IBM Global SUR Award Program; European Research Council FP7 Project SUNNY [313243]; KAUST; SCI(E); ARTICLE; 3; 486-500; 39 |
