We apply the semantic segmentation method in deep network to high precision satellite image change detection, and propose a network framework to improve the detection performance.We directly processed the image after registration, without the steps of radiometric correction, and avoided the tedious steps of manual feature design by traditional methods.We tried to use Unet and Deeplab v3 model to divide the change area, and added the structure of jumping connection on the basis of Deeplab network, which made the edge of the detection graph more accurate and improved the performance of the network.The test results show that this method is effective for detecting the change of highprecision remote sensing images.
Semantic segmentation is one of the basic themes in computer vision. Its purpose is to assign semantic tags to each pixel of an image, which has been applied in many fields such as medical field, intelligent transportation and remote sensing image. In this paper, we use deep learning to solve the task of remote sensing semantic image segmentation. We propose an algorithm for semantic segmentation of the Attention Seg-Net network combined with SegNet and attention gate. Our proposed network can better segment vegetation, buildings, water bodies and roads in the test set of remote sensing images.
SSD (Single Shot Multi-box Detector) is one of the best object detection algorithms with both high accuracy and fast speed. However, SSD’s feature pyramid detection method only extracts the features from different scales without further procession, which leads to semantic information lost. In this paper, we proposed Multi-scales Feature Integration SSD, an enhanced SSD with feature integrated modules which can improve the performance significantly over SSD. In the feature integrated modules, features from different layers with different scales are concatenated together after some upsampling tricks, then we use the features as input of several convolutional modules, those modules will be fed to multibox detectors to predict the final results. We test our algorithm On the Pascal VOC 2007test with the input size 300×300 using a single Nvidia 1080Ti GPU. In addition, our network outperforms a lot of state-of-the-art object detection algorithms in both aspects of accuracy and speed.
