In this paper, we have designed a new method for region based retrieval of textured monochannel images. To perform segmentation and region featureextraction, the concept of Markov Random Fields (MRF) in the Wavelet Transform (WT) domain is considered and the Iterated Conditional Modes (ICM) algorithm is employed. The novelty of our approach consists in exploiting the hierarchical organization of features through scales and iterations in order to design a multiresolution and iteratively refined search procedure until user satisfaction. Experimental results show that our method achieves a suitable tradeoff between complexity and reliability of the search procedure.
