A cortical model for motion-in-depth selectivity of complex cells in the visual cortex is proposed. The model is based on a time ex(cid:173) tension of the phase-based techniques for disparity estimation. We consider the computation of the total temporal derivative of the time-varying disparity through the combination of the responses of disparity energy units. To take into account the physiological plau(cid:173) sibility, the model is based on the combinations of binocular cells characterized by different ocular dominance indices. The resulting cortical units of the model show a sharp selectivity for motion-in(cid:173) depth that has been compared with that reported in the literature for real cortical cells.
