Remote sensing change detection model based on multi-scale fusion
The remote sensing image change detection model which is based on multi-scale fusion is proposed to accurately identify the change region of the bi-temporal remote sensing images.First,a multi-scale input pyramid is constructed in the feature extraction stage to receive multi-layer receptive fields and enhance the perception of all information.Then,in order to make a tradeoff between locating the changing area and mining details,the multi-scale calculation is carried out for deep difference features.Finally,the semantic change information can be identified and retained to a great extent by integrating the different feature results of the network.The experimental results show that the proposed model has good performance in both subjective evaluation and objective indexes.
