Remote Sensing Map Compression Method Based on Structure Feature Preserving Network
In the practical applications of remote sensing maps
rich structural and texture information is often required. However
some structural information may be ignored or smootheddue toimagecompressionduring the transmission process
resulting intheblurred edges or distorted spatial relationshipsin the remote sensingmaps. To address theaforementionedissues
this paper proposes a remote sensing map compression method based on a structure feature preservingnetwork.This network consists of an edge texture preservingsub-network and a global structure fusion sub-network.In theedge texture preservingsub-network
the significant edges and detailed texture features of the image are preserved by using a gray-level co-occurrence matrix and edge feature extraction to guide the neural network
anda spatial structure enhancement moduleis usedto enrich the detailed information.In theglobal structure fusion sub-network
a coarse-to-fine network architecture designis usedto fully understand the global structural correlation of the image and more effectively remove redundant information. Finally
the output features of the above sub-networks are fused to take into account both the local edge texture and the global structural correlation of the remote sensing map. Experimental results show that the proposed method significantly reduces the loss of structural features in the compression process of remote sensing maps.
