Research in texture recognition often concentrates on the problem of material recognition in uncluttered conditions, an assumption rarely met by applications. In this work we conduct a first study of material and describable texture attributes recognition in clutter, using a new dataset derived from the OpenSurface texture repository. Motivated by the challenge posed by this problem, we propose a new texture descriptor, \dcnn, obtained by Fisher Vector pooling of a Convolutional Neural Network (CNN) filter bank. \dcnn substantially improves the state-of-the-art in texture, material and scene recognition. Our approach achieves 79.8\% accuracy on Flickr material dataset and 81\% accuracy on MIT indoor scenes, providing absolute gains of more than 10\% over existing approaches. \dcnn easily transfers across domains without requiring feature adaptation as for methods that build on the fully-connected layers of CNNs. Furthermore, \dcnn can seamlessly incorporate multi-scale information and describe regions of arbitrary shapes and sizes. Our approach is particularly suited at localizing ``stuff'' categories and obtains state-of-the-art results on MSRC segmentation dataset, as well as promising results on recognizing materials and surface attributes in clutter on the OpenSurfaces dataset.
