ABSTRACT: In this paper an evaluation of the influence
of luminance L* at the L*a*b* color space during color segmentation is
presented. A comparative study is made between the behavior of segmentation in
color images using only the Euclidean metric of a* and b* and an adaptive color
similarity function defined as a product of Gaussian functions in a modified
HSI color space. For the evaluation synthetic images were particularly designed
to accurately assess the performance of the color segmentation. The testing
system can be used either to explore the behavior of a similarity function (or
metric) in different color spaces or to explore different metrics (or
similarity functions) in the same color space. From the results is obtained
that the color parameters a* and b* are not independent of the luminance
parameter L* as one might initially assume.
