Has Anything Changed? 3D Change Detection by 2D Segmentation Masks

Autor: Adam, Aikaterini, Karantzalos, Konstantinos, Grammatikopoulos, Lazaros, Sattler, Torsten

As capturing devices become common, 3D scans of interior spaces are acquired on a daily basis. Through scene comparison over time, information about objects in the scene and their changes is inferred. This information is important for robots and AR a

Very Deep Super-Resolution of Remotely Sensed Images with Mean Square Error and Var-norm Estimators as Loss Functions

Autor: Panagiotopoulou, Antigoni, Grammatikopoulos, Lazaros, Charou, Eleni, Bratsolis, Emmanuel, Madamopoulos, Nicholas, Petrogonas, John

In this work, very deep super-resolution (VDSR) method is presented for improving the spatial resolution of remotely sensed (RS) images for scale factor 4. The VDSR net is re-trained with Sentinel-2 images and with drone aero orthophoto images, thus
