Food-Classification

This Social Media Management project allow to classificate picture between food and non-food.

What we do:

  1. Extract feature splitted 70% for training and 30% test set.
  2. With deasy (step=8) extract local feature.
  3. To build aur dictionary of visual word, we have cluster all local feature with KMeans=500 (scikitlearn).
  4. Finally to classificate the picture we have used KNN.

Bag of visual word

In computer vision, the bag-of-words model (BoW model) can be applied to image classification, by treating image features as words. In document classification, a bag of words is a sparse vector of occurrence counts of words; that is, a sparse histogram over the vocabulary. In computer vision, a bag of visual words is a vector of occurrence counts of a vocabulary of local image features.
