WebApr 26, 2015 · Image Fisher Vector In Python Although the state of the art in image classification is deep learning, Bag of words approaches still perform well on many image datasets. Fisher vectors is the state of the art in that approach, allowing training more discriminative classifiers with a lower vocabulary size.
