Differential feature distribution maps for image segmentation andregion queries in image databases

摘要

We present a novel region segmentation framework, dedicated toregion queries in content based image retrieval. Some of the featuresthat are considered for image indexing are used for segmenting the imagein a few regions of interest. The novelty of our technique comes fromthe unification of the feature space and the image space segmentation ina common framework. The method uses no prior modeling of the image,focusing on local feature distributions and their spatial stability in amulti feature, multi resolution approach. Several experiments arepresented on real world imagery, demonstrating the power of the methodfor segmentation and region queries in image databases
