Abstract

En 中文

Multilabel image recognition, a critically practical task in computer vision, aims to predict multiple objects present in each image. The existing studies mainly focus on conceptual visual cues but fail to reconcile the visual information with their semantic guidance. Intuitively, humans can not only associate extra topological concepts but also imagine other approximate scenes based on a semantic description. Inspired by such semantic-interactive capability, two different types of semantic priors, i.e., the concept correlations of the same scene and semantic similarities among different scenes, should be further explored for the recognition decisions. To efficiently interact with these semantic relationships, in this article, we propose a novel semantic-interactive graph convolutional network (SI-GCN), which can leverage the topological information learned from knowledge graphs to boost the performance of multilabel recognition. Specifically, the proposed SI-GCN framework consists of two different GCN-based branches in parallel, i.e., concept correlations learning (CCL) branch and semantic similarity learning (SSL) branch. Inputting the semantic-embedding vectors of all the concepts, the CCL branch maps the label co-occurrence graph into a set of interdependent concept classifiers. Recalibrating the image feature embedding with the standardized supervision of the semantic similarity graph, the SSL branch learns the semantically consistent in-batch visual representations. Finally, a well-established interactive learning scheme is formulated to concurrently optimize the obtained concept classifiers and the visual representation learning in an end-to-end manner. Extensive experiments on the MS-COCO and Pascal VOC 2007 & 2012 benchmarks demonstrate the superiorities of the proposed SI-GCN method compared to the state-of-the-art baselines.
