COCO Attributes: Attributes for People, Animals, and Objects

ECCV 2016  ·  Genevieve Patterson, James Hays ·

In this paper, we discover and annotate visual attributes for the COCO dataset. With the goal of enabling deeper object understanding, we deliver the largest attribute dataset to date. Using our COCO Attributes dataset, a fine-tuned classification system can do more than recognize object categories -- for example, rendering multi-label classifications such as ''sleeping spotted curled-up cat'' instead of simply ''cat''. To overcome the expense of annotating thousands of COCO object instances with hundreds of attributes, we present an Economic Labeling Algorithm (ELA) which intelligently generates crowd labeling tasks based on correlations between attributes. The ELA offers a substantial reduction in labeling cost while largely maintaining attribute density and variety. Currently, we have collected 3.5 million object-attribute pair annotations describing 180 thousand different objects. We demonstrate that our efficiently labeled training data can be used to produce classifiers of similar discriminative ability as classifiers created using exhaustively labeled ground truth. Finally, we provide baseline performance analysis for object attribute recognition.
