Webapproximation of the Fisher vector is derived. Then, the performance of the Fisher vector is signiﬁcantly improved in [5] by using power normalization and ℓ2 normalization. The Fisher vector framework has achieved promising results and is becoming the new standard in both image classiﬁcation [5] and image retrieval tasks [6]–[8].
