Abstract:

Image segmentation method based on region growing suffers the problem of selecting appropriate growing seeds and segmentation parameters.A segmentation method based on a novel kind of region-merging probability measure is proposed to solve the problem in this paper.First,an initial segmentation is achieved by marker-based watershed transformation and simple region merging.Statistic,context and shape information can be calculated from the initial segmentation regions.Then a scale-independent merging probability of neighboring regions is calculated by the information based on Bayesian criterion,which is integrated into sequential region merging procedure.It is easier to determine a threshold value for the new probability measure because of its intuitive meaning.And multi-scale objects can be simultaneously segmented in once segmentation,since the probability is independent of scale.Experiment shows a good performance of the method by visual and quantitative analysis and compared with multi-resolution segmentation results of eCognition.
