Jianping Fan, Hangzai Luo, Yi Shen, Chunlei Yang
2009 Proceeding of the ACM International Conference on Image and Video Retrieval - CIVR '09  
First, a topic network is generated to characterize both the semantic similarity contexts and the visual similarity contexts between the image topics more sufficiently.  ...  similarity contexts between their tags for topic network generation and word sense disambiguation.  ...  Thus it is necessary to exploit both the inter-topic semantic contexts and the inter-topic visual contexts for generating a more precise topic network.  ...

A two-tier semantic overlay network for P2P search

Tao Gu, Daqing Zhang, Hung Keng Pung
2007 2007 International Conference on Parallel and Distributed Systems  
Context data with the same semantics are grouped together into a one-dimensional semantic ring space in the upper-tier network.  ...  Thus, all the nodes in the same semantic cluster know which node is responsible for storing context data triples they are looking for, and context queries can be efficiently routed to those nodes.  ...  With this scheme, a peer can extract the semantics of its data triples more precisely without losing generality for context queries.  ...

Context aware saliency map generation using semantic segmentation [article]

Mahdi Ahmadi, Mohsen Hajabdollahi, Nader Karimi, Shadrokh Samavi
2018 arXiv   pre-print
Saliency map from semantic information is fused with color and contrast based saliency maps. The final saliency map is then generated.  ...  Saliency map detection, as a method for detecting important regions of an image, is used in many applications such as image classification and recognition.  ...  CNN produces both the semantic segmentation and the image context. Two other saliency maps are also generated based on color and contrast.  ...

An Ontology-Based P2P Network for Semantic Search

Tao Gu, Daqing Zhang, Hung Keng Pung
2009 International Journal of Grid and High Performance Computing  
Thus, all the nodes in the same semantic cluster know which node is responsible for storing context data triples they are looking for, and context queries can be efficiently routed to those nodes.  ...  This is achieved by applying an ontology-based semantic clustering technique and dedicating part of node identifiers to correspond to their data semantics.  ...  With this scheme, a peer can extract the semantics of its data triples more precisely without losing generality for context queries.  ...

Semantic Context-Aware Image Style Transfer

Yi-Sheng Liao, Chun-Rong Huang
2022 IEEE Transactions on Image Processing  
To achieve semantic context-aware style transfer, a hierarchical local-to-global network architecture, which contains two sub-networks including the local context network and the global context network  ...  The former focuses on style transfer for each semantic context pair from the style image to the content image, and generates a local style transfer image storing the detailed style feature representations  ...  Second, a novel hierarchical local-to-global network architecture is developed to enhance the stokes of local semantic context pairs and generate a globally consistent stylized result.  ...

Noorhan Khaled, M Aref, mohammed marey
2021 International Journal of Intelligent Computing and Information Sciences  
Secondly, we propose to explicitly extract bi-modal semantic concepts (nouns and verbs) from a detected event segment and equilibrate the contributions from the proposed event representation and the semantic  ...  Most recent works attempted to make use of an encoder-decoder neural network framework which employs a 3D-CNN as an encoder for representing a detected event frames, and an RNN as a decoder for caption  ...  Also learning bi-modal semantic features via attending on relevant verbs and nouns that describes the event content effectively, improves the captioning performance and is done while decoding each event  ...
