These image representations are also produced from local descriptors, yet they propose an alternative aggrega-tion stage, which replaces bag-of-words histograms. They are both built as the concatenation of sub-vectors (SIFT-like in case of VLAD), one per visual-word. One of their

WebVLAD [20] or Fisher vector [28] with SIFT features [25]. By replacing SIFT by features extracted from convolu-tional layers of a deep network pre-trained on ImageNet [9], these models achieve state-of-the-art results on a number of recognition tasks [7]. These models capture local fea-ture interactions in a translationally invariant manner which WebIt also generalizes various orderless texture descriptors such as the Fisher vector, VLAD and O2P. We present experiments with bilinear models where the feature extractors are based on convolutional neural networks. The bilinear form simplifies gradient computation and allows end-to-end training of both networks using image labels only.
