Abstract In this report, we propose a method of Text-Based Image Retrieval(TBIR) using Earth Mover's Distance(EMD). Our approach uses EMD to combine textual and visual features into one semantic space, to improve the performance of TBIR. We compare our method with four conventional methods including LSI and PLSI. The results show our method is superior to others in average precision. We also applied an approximation in computing EMD for improving the efficiency of the proposed method. The results show that the approximate method can reduce the computational complexity in about 8%, with little loss of average precision.
