Self-organizing feature map with position information and spatial frequency information

The representation of scale - position information of local features in images is discussed. A feature map is proposed on which scale information is represented in position explicitly in the same manner of position information. The result of a computer simulation to self-organize such a feature map by using a retina-like filter set in the case of one-dimensional input data is shown. This feature map seems useful for scale invariant image recognition.<
