Embodiment Construction
[0020] Below in conjunction with accompanying drawing, the present invention is described in more detail:
[0021] Step 1: Use the NCut (Normalized Cut) image segmentation algorithm to segment the training image (annotated image for learning) and the test image respectively to obtain a visual description of the image area.
[0022] Step 2, Construct all images used for learning {J 1 ,·,J l}PC train The visual nearest neighbor graph of The vertex set V corresponds to each image, each vertex corresponds to an image, and the edge set E represents the visual distance between images. We use the similarity measure of multi-region integrated matching for the visual distance between images - Earth Mover's Distance (EMD), and the weight on the edge connecting two vertices corresponds to the EMD visual distance between images.
[0023] Step 3, in the training image set, each image has a set of initial normalized tag word weight vectors. The normalization method of the weight vecto...
