Transductive Semisupervised Deep Hashing

IEEE Transactions on Neural Networks and Learning Systems, 2022
Deep hashing methods have shown their superiority to traditional ones. However, they usually require a large amount of labeled training data for achieving high retrieval accuracies. We propose a novel transductive semisupervised deep hashing (TSSDH) method which is effective to train deep convolutional neural network (DCNN) models with both labeled and

Deep Video Hashing

IEEE Transactions on Multimedia, 2017
In this work, we propose a deep video hashing (DVH) method for scalable video search. Unlike most existing video hashing methods that first extract features for each single frame and then use conventional image hashing techniques, our DVH learns binary codes for the entire video with a deep learning framework so that both the temporal and ...

Deep hashing learning networks

2016 International Joint Conference on Neural Networks (IJCNN), 2016
Hashing-based methods seek compact and efficient binary codes that preserve the similarity between data. For most existing hashing methods, an input (e.g. image) is first encoded as a vector of hand-crafted visual feature, followed by a hash projection and quantization step to obtain the compact binary vector.

Asymmetric Deep Hashing for Efficient Hash Code Compression

Proceedings of the 28th ACM International Conference on Multimedia, 2020
Benefiting from recent advances in deep learning, deep hashing methods have achieved promising performance in large-scale image retrieval. To improve storage and computational efficiency, existing hash codes need to be compressed accordingly. However, previous deep hashing methods have to retrain their models and then regenerate the whole database ...

Deep Image Set Hashing

2017 IEEE Winter Conference on Applications of Computer Vision (WACV), 2017
In applications involving matching of image sets, the information from multiple images must be effectively exploited to represent each set. State-of-the-art methods use probabilistic distribution or subspace to model a set and use specific distance measure to compare two sets.

Deep Semantic Asymmetric Hashing

2019
Deep hashing, which combines binary codes learning and convolutional neural network, has achieved promising performance for highly efficient image retrieval. Asymmetric deep hashing methods, which treat query points and database points in an asymmetric way perform better than symmetric deep hashing methods on retrieval tasks in both time complexity and
