Embodiment 1
[0143] refer to Figure 1-11 , the technical solution adopted by the present invention to solve its technical problems is:
[0144] An end-to-end approach to image retrieval via hierarchical deep search based on deep convolutional neural networks includes a convolutional neural network for deep learning and trained recognition, a fast visual segmentation algorithm for searching image objects, a method for coarse search A method for fast image alignment using hashing and Hamming distance and an exact alignment method for top-k ranked images based on images from candidate pool P;
[0145] (1) About designing a fast visual segmentation algorithm for searching image objects;
[0146] Since in most applications, the search image object is only a part of the whole image, especially in road monitoring and bayonet image comparison search, it is necessary to design a fast visual segmentation algorithm for search image objects to improve search efficiency ;
[0147] First, a fast vis...
Embodiment 2
[0254] The technology of image search in the present invention has universal applicability, and is suitable for network image search engine, video investigation and bayonet analysis and judgment, as long as the image data participating in the training is operated in the system developed by the present invention to learn, and obtain such objects (such as a specific person, a specific vehicle, etc.) after the characteristics of the search task can be realized.
