Embodiment 1
[0054] Embodiment 1: as figure 1 As shown, an image retrieval method based on multi-feature fusion and diffusion process reordering, this embodiment takes an image database composed of N (1000) images with a size of m×n (192×168) as an example, each The images are used as query images respectively, and the retrieval is completed by obtaining the similarity between each query image and other images in the database. The specific process includes: extracting the features of all images (Step1) and performing normalization and fusion (Step2), calculating the distance matrix between image features (you can get the similarity between each query image and other images in the database, the closer the distance The smaller the image, the more similar the image), and then introduce the diffusion process to optimize the distance matrix (Step3), and finally reorder it and complete the retrieval (Step4).
[0055] In the retrieval process, the present invention proposes an image feature extr...
