Image processing in early vision involves complex computational tasks,
such as convolution operations with elongated Gaussian or Gabor-like
functions. We show how these operators can be related to the signal
processing capabilities of 2D active resistor grids characterized by
anisotropicpatterns of interconnections. Applications to texture
segregation are described.
