Event Details

European Space Imaging and our partner, Maxar, are excited to present our final GEOSeries webinar for 2022. Join us as we present you with 15cm HD satellite imagery; a proprietary technology from Maxar that intelligently increases pixel resolution to enhance clarity and feature detection so that you can make more informed decisions from satellite imagery. Gain insights into the background and development of 15cm HD imagery, what you can achieve with this product and see examples first hand. Additionally, military experts will give further perspective on the benefits of this product for increasing situational awareness, explaining the differences between standard imagery and 15cm HD imagery.

Architecture of ResNet34-UNet model

UNet architecture for semantic segmentation with ResNet34 as encoder or feature extraction part. ResNet34 is used as an encoder or feature extractor in the contracting path and the corresponding symmetric expanding path predicts the dense segmentation output.

Architecture of VGG16-UNet model

UNet architecture for semantic segmentation with VGG16 as the encoder or feature extractor. VGG16 is used as an encoder or feature extractor in the contracting path and the corresponding symmetric expanding path predicts the dense segmentation output.

Architecture of ResNet34-FCN model

In this model, ResNet34 is used for feature extraction and the FCN operation remains as is. The feature of ResNet architecture is exploited where just like VGG, as the number of filters double, the feature map size gets halved. This gives a similarity to VGG and ResNet architecture while supporting deeper architecture and addressing the issue of vanishing gradients while also being faster. The fully connected layer at the output of ResNet34 is not used and instead converted to fully convolutional layer by means of 1×1 convolution.

Architecture of VGG16-FCN model

In this model, VGG16 is used for feature extraction which also performs the function of an encoder. The fully connected layer of the VGG16 is not used and instead converted to fully convolutional layer by means of 1×1 convolution.
