Images as Bags of Pixels

  title={Images as Bags of Pixels},
  author={Tony Jebara},
We propose modeling images and related visual objects as bags of pixels or sets of vectors. For instance, gray scale images are modeled as a collection or bag of (X,Y, I) pixel vectors. This representation implies a permutational invariance over the bag of pixels which is naturally handled by endowing each image with a permutation matrix. Each matrix permits the image to span a manifold of multiple configurations, capturing the vector set’s invariance to orderings or permutation transformations… CONTINUE READING
