| Abstract | Most segmentation algorithms have explicit parameters that must be properly set in order to produce the desired outcome, and the definition of suitable parameter values is usually a complex, time consuming task. In Costa et al. (2008), a supervised, semi-automatic parameter adaptation method based on a Genetic Algorithm (GA) was proposed. Given an initial set of reference object samples, the method searches the parameter space for (near) for values that will produce segments as similar as possible to the reference. The specific formulation of the objective function, which provides the similarity measure used in the method, privileged applications in which the objects to be segmented were homogeneous. This work addresses this issue, extending the previous work by proposing a novel objective function which considers the objects of interest to be inhomogeneous, though formed by an assembly of homogeneous parts. The software prototype that implemented the previous approach was extended with the new objective function, and an experimental evaluation of the two objective functions were performed taking into account three different segmentation algorithms and five different object classes. The analysis of the results obtained with both objective functions provides guidelines for the selection of the function to be used in different applications. | ||||||
