| Abstract: Mask RCNN,the state-of-the-art instance segmentation algorithm,is adopted in the building extraction from high-resolution remote sensing imagery.The paper proposes an efficient and accurate building extraction method from high-resolution remote sensing imagery.Firstly,Tensorflow and Keras deep learning framework are used to build the Mask RCNN network model;then,the model learning is carried out on the IAILD data set by supervised learning.By using the trained model,the experiment of building extraction is carried out on the test set.By comparing with the building extraction methods,such as KNN and SVM,it can be seen that this method can be more complete and accurate to extract the building. The mAP evaluation index is used to evaluate the experimental results quantitatively.The recall and precision of the algorithm are all larger than the contrast algorithms,and the mAP of the algorithm is more than 81% in this paper,which verifies the validity and accuracy of the high resolution remote sensing image building extraction based on convolution neural network. |
