Input image
Figure 5.7: Likelihood response of the S3 nodes, A (S3), at all locations and RF si/es of Ihe
alternative 3-luyer archiwciiire. The input image used was the 24th ohject of the
dataset, which corresponds to S3 stiiics 93 to 96 of the 24(1 slates. Kc[:all in this
architeciurc there are fttur S3 prototypes for each ohjeci, corresponding to four
dilfereni possible lot;ations of the ohject al the C2 level. An imagi; next to the
maximum value of each dislrihution is .shown to symbolically represent the winner
S3 prototype. Note that in most cases the winner element corresponds to a
prototype of the input image. However, in some cases there might exist some ambiguity
and oiher similar objeci prototypes may exhibit relatively large values. For
example, for location (2,2) of KF size=4x4, the prototypes of the letters M and W
also showed relatively high values. The bottom-left distribution shows the mean
S3 likelihood response over the 2x2 locations and the four RF sizes.
