CNN Features for Image Retrieval

• Low dimensional CNN (LDCNN)

This is the implementaton of the paper "Learning low dimensional convolutional neural networks for high-resolution remote sensing image retrieval ".

LDCNN is a CNN architecture consisting of common convolutional layers and the mlpconv layer used  in Network in Network (NIN).  The features extracted by the pre-trained CNNs like AlexNet, VGG, etc., from the fully-connected layers are usually 4096-D, while LDCNN can learn low dimensional features   and generally have better performance than the pre-trained CNNs. The matlab implementation is   available on GitHub!

We also provide some finetuned CNNs (CaffeRef, VGGM, VGGS) and the trained LDCNN to replicate the results in Table 10.  The finetuned CNNs and LDCNN are trained on AID dataset and then evaluated on UCMD, RSD and RSSCN7 datasets.
