Semantics-Preserving Bag-of-Words Models and Applications

open access: yesIEEE Transactions on Image Processing, 2010
The Bag-of-Words (BoW) model is a promising image representation technique for image categorization and annotation tasks. One critical limitation of existing BoW models is that much semantic information is lost during the codebook generation process, an important step of BoW.
