Sparse Approximation of Images Inspired from the Functional Architecture of the Primary Visual Areas
Modeling of simple cells through a sparse overcomplete gabor wavelet representation based on local inhibition and facilitation
We present a biologically plausible model of simple cortical cells as 1) a linear transform representing edges and 2) a non-linear …
