Embodiment 1
[0037] Datasets: Two popular datasets are used as the retrieved datasets, namely the Holiday dataset and the DupImage dataset. Among them, the Holiday dataset contains a total of 1491 images, and the approximate number of repeated image groups is 500; while the DupImage dataset contains a total of 1104 partially repeated images, with a total of 33 groups. In addition, in order to make the example more realistic, this embodiment also specially adopts the confusing image dataset MIRFlickr1M, which contains one million irrelevant images downloaded from web pages. In this embodiment, a picture in each retrieved data set is used as a target picture, and other pictures of the same group are mixed into the confused picture, so as to test the retrieval effect.
[0038] Evaluation indicators: In this embodiment, the general average retrieval accuracy (mAP) and average retrieval time that can reflect the performance of image retrieval are used to test and compare the present invention w...
