To be used effectively in visual pattern recognition, SMFs must be used in large neural arrays, as shown in Figure 7.2-3. Some elemental image, sk(x, y) impinges on the sensory array. It is processed in parallel by N, different SMFs, the outputs of each are normalized by dividing by Ek, the image's "energy."
Ek = fjj sk (x, y)|2dxdy = fjj Sk (u, vfdudv 7.2-23
SMFs Nonnalizers sk(x, y)
