The FMMIS global performance on the test set, and its per-category disaggregation are shown in the Table. The global TP rate achieved 95 percent of the total defects present in the test set, while the FP rate was 6 percent of the total grain lines (clear wood) present in the test set. On average, the number of selected seeds per image was about 100, i.e., 0.1 percent of the total number of pixels of an image. This fact makes the FMMIS algorithm very fast. The last column shows the average processing time for FMMIS, including the seed selection process, which reached 0.11 +/- 0.04 seconds per image.
