On the Expected Size of the 2D Visibility Complex
We study the expected size of the 2D visibility complex of randomly distributed objects in the plane. We prove that the asymptotic expected number of free bitangents (which corres...

A recurrent network model for the phase invariance of complex cell responses
Cortical amplification is a mechanism for modifying the selectivity of neurons through recurrent interactions. Although conventionally used to enhance selectivity, cortical amplif...

Estimating Local Surface Complexity Maps Using Spherical Harmonic Reconstructions
Abstract. Cortical surface complexity is a potential structural marker for certain diseases such as schizophrenia. In this study, we developed a measure of fractal dimension (FD) c...
