Abstract:

Retrieval task of scene landmark matching mainly solves the retrieval and matching problem of geographical targets under the conditions of view angle change, illumination change, and even occlusion. It is also called instance target retrieval. In this paper, we design a three streams' siamese network architecture with high performance convolutional network, the triple loss function, and the regional proposal network is used to accurately define the target area, so generate a accurate and robust image feature representation with fixed length. According to the characteristics of the scene landmark matching, the global features of the image are used for coarse retrieval, and the local features are used for fine retrieval. And combined with the query expansion method, accurate instance target retrieval is achieved. Experiments show that compared with other representative retrieval methods, this method can achieve competitive results in public data set testing.

Key words: convolutional network, landmark matching, siamese network architecture, triplet loss function, instance target
