Abstract  The image features learned by deep convolutional neural networks have an obvious hierarchical structure. As the number of layers deepens, the learned features become more and more abstract and the discrimination of classes is gradually enhanced. Based on the above, deep hamming embedding based hashing for image retrieval is proposed. A hidden layer is inserted at the end of the deep convolutional neural network and then hash codes are obtained by the activation of each unit of the layer. According to the characteristics of hash codes, hamming embedding loss is proposed to preserve the similarity between the original data better. Experiments on commonly used benchmark image datasets CIFAR-10 and NUS-WIDE indicate that the proposed model improves image retrieval performance and performs better with short encoding length.
