Visual word disambiguation by semantic contexts

Yu Su, Frederic Jurie
2011 2011 International Conference on Computer Vision  
On the other hand, an image is represented by the occurrence probabilities of semantic contexts.  ...  On one hand, for an image, multiple contextspecific bag-of-words histograms are constructed, each of which corresponds to a semantic context.  ...  Polysemy of visual words is partly caused by the discard of spatial information. Hence, the use of spatial information can also help to disambiguate visual words.  ...

Contextual object categorization with energy-based model [article]

Changyong Ri, Duho Pak, Cholryong Choe, Suhyang Kim, Yonghak Sin
2016 arXiv   pre-print
Object categorization is a hot issue of an image mining. Contextual information between objects is one of the important semantic knowledge of an image.  ...  Then, the spatial relations were considered as well as co-occurrence and appearance of objects by using energy-based model, where the energy function was defined as the region-object association potential  ...  with co-occurrence and spatial constraints of objects in an image.  ...

Context based object categorization: A critical survey

Carolina Galleguillos, Serge Belongie
2010 Computer Vision and Image Understanding  
Several models for object categorization use appearance and context information from objects to improve recognition accuracy.  ...  The goal of object categorization is to locate and identify instances of an object category within an image.  ...  The majority of the context-based models include at most two different types of context, semantic and spatial, since the complexity to determine scale context is still high for 2D images.  ...

Visual pattern discovery in image and video data: a brief survey

Hongxing Wang, Gangqiang Zhao, Junsong Yuan
2013 Wiley Interdisciplinary Reviews Data Mining and Knowledge Discovery  
In image and video data, visual pattern refers to re-occurring composition of visual primitives. Such visual patterns extract the essence of the image and video data that convey rich information.  ...  However, unlike frequent patterns in transaction data, there are considerable visual content variations and complex spatial structures among visual primitives, which make effective exploration of visual  ...  . 38, 60 Classic Topic Model for Visual Pattern Discovery The topic model, such as LDA 15 and probabilistic latent semantic analysis (pLSA), 92 discovers semantic topics from a corpus of documents  ...

Context-aware image semantic extraction in the social web

Massimiliano Ruocco
2012 Proceedings of the 21st international conference companion on World Wide Web - WWW '12 Companion  
With the advent of the paradigm of Web 2.0 especially the past five years, the concept of image context has further evolved, allowing users to tag their own and other people's pictures.  ...  Focusing on tagging, we distinguish between static and dynamic features. The set of static features include textual and visual features, as well as the contextual information.  ...  Tour Eiffel) and visual description (sunset, sky). For this purpose the features used to mine the dataset was time, location, visual information and tags co-occurrence.  ...
