In this work, we present an objective evaluation using metrics, for the evaluation we implemented three MPEG-7 descriptors present in LIRe and we proposed an adjustment for the metric ANMRR. Since this metric punishes the evaluation when the total recovered images are less than the class of the query image. To improve the ANMRR metric evaluation, we proposed an adjustment considering the number of recovered images. The results showed which descriptor presented a better evaluation in each one metrics, as well as the difference between the most popular evaluation metrics used in image retrieval systems and the proposed ANMRR metric. This simple adjustment of ANMRR appears to be a good evaluation alternative for cases where the recovered images are less than the class of the query.
