Abstract: The preliminary research indicates that the gray level co-occurrence matrix display the better retrieval effect in the sternum image retrieval and relevance feedback realizing man machine interactive retrieval can effectively enhance the efficiency.In this paper two feedback methods with moving inquiry have further compared.First，retrieval with the piecemeal texture，then retrieval with Rocchio feedback method and based on minimal Bayesian error rate feedback method.Experiment proves that based on minimal Bayesian error rate feedback method can reduce “the meaning gap”，enhance the retrieval efficiency.
