These evaluation criteria can be used to define new image processing algorithms by optimizing them. In this paper we propose a general scheme to segment images by a genetic algorithm. The developed method uses an evaluation criterion which quantifies the quality of an image segmentation result. The proposed segmentation method can integrate a local ground truth when it is available in order to set the desired level of precision of the final result. A genetic algorithm is then used in order to determine the best combination of information extracted by the selected criterion. Then we show that this approach can either be applied for gray-levels or multicomponents images in a supervised context or in an unsupervised one. Last we show the efficiency of the proposed method through some experimental results on several gray-levels and multicomponents images. Copyright 2008 S. Chabrier et al.
