There are many problems to realize camera-based character recognition. One of the problems is that characters in scenes are often distorted by geometric transformations such as af...

We introduce an (equi-)affine invariant diffusion geometry by which surfaces that go through squeeze and shear transformations can still be properly analyzed. The definition of an...

The problem of shape-based recognition of objects under affine transformations is considered. We focus on the construction of a robust and highly discriminative affine invariant...
