Results - Word Spotting
Word spotting is when you have several examples in which you know a sign occurs and you have to locate the sign. We found the ground truth for some data and ran the mining with a buffer of 50 frames applied to either side of the sign. This was to ensure that if we had good labels the system would indeed work. During this stage the parameters for mining were found experimentally on the Army data and applied to the Plane data. As shown in the figures below the mining was able to find and segment the signs.
Figure 7 - Results for 10 examples of the sign Army/Soldier, the mining responses peak on 7 of the signs with no false positives.
Figure 8 - Results for 7 examples of the sign Plane, the mining responses peak on 6 of the signs with 1 false positive.
