Differential feature distribution maps for image segmentation and region queries in image databases
A. Nicole Winter, Chahab Nastar · 2003
We present a novel region segmentation framework, dedicated to region queries in content based image retrieval. Some of the features that are considered for image indexing are used for segmenting the image in a few regions of interest. The novelty of our technique comes from the unification of the feature space and the image space segmentation in a common framework. The method uses no prior modeling of the image, focusing on local feature distributions and their spatial stability in a multi feature, multi resolution approach. Several experiments are presented on real world imagery, demonstrating the power of the method for segmentation and region queries in image databases.
