Content-based image retrieval algorithm (CBIR) aims to find semantically matching or similar images with query images. It analyzes visual content in a large number of image databases. It is important to obtain discriminant image representation by feature extraction. With the continuous development of deep learning, the image feature representation method used in image retrieval has gradually changed. The original extraction method is based on manual features. Now it is based on deep features. From the perspective of different feature extraction methods, the recent image retrieval algorithms based on depth feature are reviewed and traced. The image retrieval algorithms based on depth feature are divided into two aspects: depth global feature and depth local feature. The deep convolution feature aggregation technique is emphasized in the deep local feature algorithm. The widely used image retrieval methods of deep global and local feature fusion are summarized. This paper discusses the practical application of deep feature image retrieval technology in remote sensing image retrieval, e-commerce product retrieval and medical image retrieval. And it compares the performance of these feature extraction algorithms in image retrieval accuracy. Finally, the future research trend of depth feature extraction in case image retrieval is forecasted.
