  1. Global and partial map search results are shown. FT, the fraction of correct maps within the first tier (top|C|−1 maps, where |C| represents the number of maps in the same class as the query map); ST, the fraction in the second tier (top 2*(|C|−1) maps). VESPER (DOT) is the results of VESPER using the DOT score. For the Laplacian filter, cross correlation was computed after the filter was applied to maps. gmfit used the default parameter of the gmfit program. gmfit(−64) used a “-maxsize 64” option when converting an EM map to a Gaussian mixture model using the gmconvert program. This is the parameter used in the gmfit webserver. The number in bold shows the best performance for each metric.
