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.

Abstract
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.
