Yan Zhou, Lili Pan, Rongyu Chen, Weizhi Shao
2020 Journal of Information Hiding and Privacy Protection  
Secondly, the information gain rate method is used to filter the extracted deep features to reduce the feature dimension and ensure the information loss is small.  ...  However, the deep feature dimensions obtained by Deep Convolutional Neural Network (DCNN) are too high and redundant, which leads to low retrieval efficiency.  ...  As thus, for image retrieval of similar objects, invariant local features with excellent anti-interference performance are usually selected, such as SIFT (Scale-Invariant Feature Transform) [4] .  ...
