Abstract: Since high-resolution images usually have features such as rich details and large category differences, current methods for remote sensing classification of convolutional neural network generally perform poorly in classification accuracy and object boundary detection. In this paper, we propose an image classification model based on enhanced DeepLabV3 network. Firstly, R-MCN is built by combing residual networks and convolution kernels of different sizes, which is used to extract multi-scale, multi-level feature information of shallow networks. Then a learnable upsampling method is used to restore image size, and fuse the features extracted by R-MCN with high-level semantic information. Finally, a loss function named Mloss is built to achieve classification results of remote sensing images. The experimental results demonstrate that the proposed method can refine object boundaries,improve classification performance,and obtain higher accuracy of image classification compared with traditional convolutional neural network.
