This paper presents a CNN-based method that is unsupervised and end-to-end trainable to better solve this task. Our method is unsupervised in the sense that it does not require any training data in the form of object masks but merely a set of images jointly covering objects of a specific class. Our method comprises two collaborative CNN modules, a feature extractor and a co-attention map generator. The former module extracts the features of the estimated objects and backgrounds, and is derived based on the proposed co-attention loss which minimizes inter-image object discrepancy while maximizing intra-image figure-ground separation. The latter module is learned to generated co-attention maps by which the estimated figure-ground segmentation can better fit the former module. Besides, the co-attention loss, the mask loss is developed to retain the whole objects and remove noises. Experiments show that our method achieves superior results, even outperforming the state-of-the-art, supervised methods.<\/jats:p>","DOI":"10.24963\/ijcai.2018\/104","type":"proceedings-article","created":{"date-parts":[[2018,7,5]],"date-time":"2018-07-05T01:49:10Z","timestamp":1530755350000},"page":"748-756","source":"Crossref","is-referenced-by-count":49,"title":["Co-attention CNNs for Unsupervised Object Co-segmentation"],"prefix":"10.24963","author":[{"given":"Kuang-Jui","family":"Hsu","sequence":"first","affiliation":[{"name":"National Taiwan University, Taiwan"},{"name":"Academia Sinica, Taiwan"}]},{"given":"Yen-Yu","family":"Lin","sequence":"additional","affiliation":[{"name":"Academia Sinica, Taiwan"}]},{"given":"Yung-Yu","family":"Chuang","sequence":"additional","affiliation":[{"name":"National Taiwan University, Taiwan"},{"name":"Academia Sinica, Taiwan"}]}],"member":"10584","event":{"number":"27","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2018","name":"Twenty-Seventh International Joint Conference on Artificial Intelligence {IJCAI-18}","start":{"date-parts":[[2018,7,13]]},"theme":"Artificial Intelligence","location":"Stockholm, Sweden","end":{"date-parts":[[2018,7,19]]}},"container-title":["Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2018,7,5]],"date-time":"2018-07-05T01:49:52Z","timestamp":1530755392000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2018\/104"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2018,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2018\/104","relation":{},"subject":[],"published":{"date-parts":[[2018,7]]}}}
