Figure 4: (a) represents an undeveloped receptive field with random initial biases. (b) represents the developed floating gate voltages or the disparity tuned receptive field after the learning phase is over. (c) shows the tuning curve for the disparity selective cell. Out of all the disparities it has the maximum response for disparity 3; therefore we say it is tuned for disparity 3. It is tuned at hwhh = 2.7 which is a good tuning measure.
