This study is aimed at the uncertainty and computational complexity of the clustering center in local image features retrieval based on the bag-of-words (BOW) model. A method to retrieve the measure of similarity degree from different kinds of distance and another method that requires using the matching point number as the basis of retrieval are proposed in this paper. In this method, the SURF feature is first modified to effectively reduce feature extraction complexity, and then FLANN (fast library for approximate nearest neighbors) bidirectional matching and KD-Tree + BBF matching are implemented for FAST + SURF features. Feature robustness is verified under different transformation conditions. Finally, all kinds of Uyghur document images that have been classified and sorted based on these two retrieval methods are retrieved. The results of the retrieval experiments indicate that the similarity degree measure retrieval based on distance is inferior to the retrieval based on matching number, and both of these two retrieval strategies can meet the requirements of fast and accurate searching.
