the difference between
Even though I have a basic understanding of the method involved (detect and extract visual words, build a visual dictionary, use machine learning to train a classifier), I still can’t see the difference between both models. Are t tommy hilfiger uk hey synonyms? Maybe I have missed concrete examples / documentation that shows the difference.At first there was the Bag of Words model for document retrieval. This model considered every document (and the query too) to be a bag of words (without ta tommy hilfiger uk king the position of each word into account). So every document was tran tommy hilfiger uk sformed into a vector of the size of the language dictionary keeping the frequency of each term (histogram)The Bag of Visual Words or Bag of Features replace the document with an image and the words with features (or “Visual Words”) and create a very similar representatio tommy hilfiger uk n of an image. So yes the BoF is synonym of the BoVW. The BoW is about text retrieval.
