Seed selection process

• To speed up the image segmentation process, the FMMIS does not use all the pixels from the image analysed. Instead, it only uses a few input pixels called seeds, to grow the hyperboxes.

• The seeds are automatically determined (located) by an ad-hoc procedure, since this process is problem-dependent.

• Considering the great variability of colour of the wood boards, the seed selection is based on adaptive thresholding in the RGB colour space.
