1. A method for detecting interest points in an image, comprising:

  • acquiring an original input image;

    performing down-sampling processing on the original input image, so as to obtain a plurality of sampling images with different resolutions;

    dividing each sampling image into a plurality of small image blocks;

    performing filtering processing on the plurality of small image blocks in each sampling image in sequence by using Laplacian-of-Gaussian filters, so as to obtain filtered images of the plurality of small image blocks in each sampling image; and

    acquiring interest points in an image in each sampling image, according to the filtered images of the plurality of small image blocks in each sampling image.
