11.7   Analysis

Possible Matches

    Let the Total Images in the input file be N, the Possible Matches will be N*N. In our example, N * N = 264 x 264 = 69,696.

Attrasoft Matches

    The number of retrieved matches is listed in the last line of b1.txt. Go to the end of  b1.txt, you will see something like this:

    Total Number of Matches = 754.

Actual Match

    This number depends on your problem. It should be the first number in b1_matchlist.txt. In our example, it is 100*4  + 120*2 + 44 x 1= 681.

Attrasoft Found Duplicates

    To check the results, we must prepare the b1_matchlist.txt file now. This file is already prepared for you and we will simply open it and save it to b1_matchlist.txt (overwrite the existing file). The steps are:

  •    Open ““c:\program files\Attrasoft 7.0/data/b1_matchlist_ex_wheel.txt. Save it to b1_matchlist.txt (overwrite the existing file). Now this file is prepared.
  •    Click “NeuralFilter/N:M Analysis/ Check(b1_matchlist.txt)” to check the results of the NeuralFilter.

    • The result is:

    Total Matches = 640 (quadruplet and doublet) + 41 (singlet)

    All of the matching images are identified. Now that you have all of the numbers, you can make an analysis.

Positive Identification Rate

    In this example, the Positive Identification Rate is 100%,  i.e., 681/681 = 100%.

Elimination Rate

    Elimination Rate = 99 % = (1 – 754/69,696).

Hit Ratio

    The Hit Ratio = 681/754 = 90 %. 

Composite Index

    The composite index is = 100% * 99% * 90% = 89%.
