Example Embodiment
[0031] Example 1:
[0032] This embodiment provides a multi-target image retrieval method, which includes the following steps:
[0033] Step 1. Input I images, take any one of the I images as image i, i=1, 2,...,I; extract M candidate targets in image i;
[0034] The deep network model constructed is: on the basis of a typical VGG-16, a number of convolutional layers of different scales (19×19×1024, 10×10×512, 5×5×256, 3×3× 256, 1×1×256), each convolutional layer extracts candidate targets through a 3×3 sliding window, where the stride is 1 and the padding is 0;
[0035] In this way, the extracted candidate targets are generated on the feature map instead of on the original image. Compared to extracting from the original image, their size is much smaller. This helps to increase efficiency and keep the model compact.
[0036] The method for obtaining candidate targets in the present invention is "W. Liu, D. Anguelov, D. Erhan, C. Szegedy, S. Reed, C.-Y. Fu, and ACBerg, "Ssd: Single sh...
