Deformable Classifiers

no code implementations18 Dec 2017 Jiajun Shen, Yali Amit

In this paper, we design a framework for training deformable classifiers, where latent transformation variables are introduced, and a transformation of the object image to a reference instantiation is computed in terms of the classifier output, separately for each class.
