Toward a higher-level visual representation for object-based image retrieval

Yan-Tao Zheng, Shi-Yong Neo, Tat-Seng Chua, Qi Tian
2008 The Visual Computer  
We propose a higher-level visual representation, visual synset, for object-based image retrieval beyond visual appearances.  ...  First, the approach strengthens the discrimination power of visual words by constructing an intermediate descriptor, visual phrase, from frequently co-occurring visual word-set.  ...  Phase 2 tackles the low discrimination issue in visual words, by exploiting the spatial co-occurrence information among visual words.  ...

Improving Content-Based Image Retrieval by Identifying Least and Most Correlated Visual Words [chapter]

Leszek Kaliciak, Dawei Song, Nirmalie Wiratunga, Jeff Pan
2012 Lecture Notes in Computer Science  
In this paper, we propose a model for direct incorporation of image content into a (short-term) user profile based on correlations between visual words and adaptation of the similarity measure.  ...  The information about the most and the least correlated visual words can be exploited in order to adapt the similarity measure.  ...  Liu et. al. ([6] ) exploit co-occurrence information in spatial domain. Authors make an assumption that the related visual words would appear in a certain neighbourhood.  ...

Consensus-Aware Visual-Semantic Embedding for Image-Text Matching [article]

Haoran Wang, Ying Zhang, Zhong Ji, Yanwei Pang, Lin Ma
2021 arXiv   pre-print
Specifically, the consensus information is exploited by computing the statistical co-occurrence correlations between the semantic concepts from the image captioning corpus and deploying the constructed  ...  Afterwards, CVSE learns the associations and alignments between image and text based on the exploited consensus as well as the instance-level representations for both modalities.  ...  With the instantiated concepts, their co-occurrence relationship are examined to build one correlation graph and thereby exploit the commonsense knowledge.  ...

Combining Multi-modal Features for Social Media Analysis [chapter]

Spiros Nikolopoulos, Eirini Giannakidou, Ioannis Kompatsiaris, Ioannis Patras, Athena Vakali
2011 Social Media Modeling and Computing  
Tagged images taken from social sites have been used in the characteristic scenarios of image clustering and retrieval, to demonstrate the benefits of multi-modal analysis in social media.  ...  In this chapter we discuss methods for efficiently modeling the diverse information carried by social media.  ...  For all images the authors released 500-dimensional co-occurrence vectors for visual words (as described in Section 4.2.1), as well as 1000-dimensional co-occurrence vectors for tag-words (as described  ...

of a word can be extended to also encompass its co-occurrence with the visual words of images it is associated with.  ...  Distributional semantic models derive computational representations of word meaning from the patterns of co-occurrence of words in text.  ...  In particular, our multimodal distributional semantic model (MDSM) exploits both co-occurrence with words (from a standard text corpus) and co-occurrence with visual features extracted using computer vision  ...

Automatic Image Annotation Using Maximum Entropy Model [chapter]

Wei Li, Maosong Sun
2005 Lecture Notes in Computer Science  
Automatic image annotation is a newly developed and promising technique to provide semantic image retrieval via text descriptions.  ...  It concerns a process of automatically labeling the image contents with a pre-defined set of keywords which are exploited to represent the image semantics.  ...  By exploiting text and image feature co-occurrence statistics, these methods can extract hidden semantics from images, and have been proven successful in constructing a nice framework for the domain of  ...

A Bayesian Approach to Hybrid Image Retrieval [chapter]

Pradhee Tandon, C. V. Jawahar
2009 Lecture Notes in Computer Science  
Content based image retrieval (CBIR) has been well studied in the computer vision and multimedia community.  ...  We fuse both of them in a Bayesian framework to design a hybrid image retrieval system by overcoming their shortcomings.  ...  On contrary, CFIR methods exploit the co-occurrence information (for example in a collaborative filtering framework) in the logs of image-access to model the similarity across images [3, 5] .  ...

High order pLSA for indexing tagged images

S. Nikolopoulos, S. Zafeiriou, I. Patras, I. Kompatsiaris
2013 Signal Processing  
This work presents a method for the efficient indexing of tagged images. Tagged images are a common resource of social networks and occupy a large portion of the social media stream.  ...  Their basic characteristic is the co-existence of two heterogeneous information modalities, i.e. visual and tag, which refer to the same abstract meaning.  ...  For all images we have used the 500-dimensional co-occurrence vectors for visual words and the 1000-dimensional cooccurrence vectors for tag-words that were released by the authors.  ...

2012 2012 19th IEEE International Conference on Image Processing  
Third, we leverage the visual and semantic correspondence and the co-occurrence patterns to improve the accuracy and efficiency for image retrieval.  ...  This paper introduces a novel approach that allows the retrieval of complex images by integrating visual and semantic concepts. The basic idea consists of three aspects.  ...  Therefore, the measure from concept co-occurrence could be more important.
