This paper proposes a new unsupervised
approach for colour image segmentation. A hierarchy of
image partitions is created on the basis of a function that
merges spatially connected regions according to primary
perceptual criteria. Likewise, a global function that measures the goodness of each defined partition is used to
choose the best low-level perceptual grouping in the hierarchy. Contributions also include a comparative study with
five unsupervised colour image segmentation techniques.
These techniques have been frequently used as a reference
in other comparisons. The results obtained by each method
have been systematically evaluated using four well-known
unsupervised measures for judging the segmentation
quality. Our methodology has globally shown the best
performance, obtaining better results in three out of four of
these segmentation quality measures. Experiments will also
show that our proposal finds low-level perceptual solutions
that are highly correlated with the ones provided by
humans [-]
