| Abstract(in English) | We previously proposed a rotation and size spreading associative neural network. The characteristics of this neural net is to spread the information of axis orientation and size of the object on surrounding space by spreading weight that has similar tuning characteristics to axis orientation neurons and size discrimination neurons in the parietal cortex. This neural net recognizes shape, orientation and size simultaneously. But the shift of the object in two-D space was not taken into consideration. In the present study, we examined the recognition characteristics of the rotation and size spreading associative neural network in two-D space. We then developed a FFT rotation, size spreading neural net. The FFT rotation, size spreading neural net recognizes the face shape in all orientation, irrespective of its position in two-D space. This net also recognizes the rotation (ranging from -75 to 75°), and size irrespective of its position in two-D space. |
