The algorithm extracts one major region, the
background of medical images representing cutaneous
pigmented regions.
• The algorithm compares all the pixels with the seed
pixel. The seed pixel values are computed as the
average values from a block of 16x16 pixels from the
top left of the image.
• The threshold values for the 3 color components are
computed as a percentage of the maximum value of the
first color component. The percentage values are
between 10% and 40%.
• For the pixel similarity the Minkowski metric is used.
