Elongatedness Explained

In image processing, elongatedness for a region is the ratio between the length and width of the minimum bounding rectangle of the region. It is considered a feature of the region. It can be evaluated as the ratio between the area of the region to its thickness squared:

elongatedness = (length)/(width) = (area)/(( 2 d) ^{2}) .

where the maximum thickness,

d , of a holeless region is given by the number of times the region can be eroded before disappearing.^[1]
