Quadruples imagery resolution of Pléiades or SPOT.
Super-resolution Pléiades/SPOT quadruples the image resolution of Pléiades and SPOT satellite imagery to increase the performance of object detection algorithms.

Super-resolution is the process of increasing the resolution of images using an algorithm. This block is based on a state-of-the-art Convolutional Neural Network algorithm. Quality improvements of the images were measured using the SSIM metric to guarantee that information content was added by the algorithm.
Image resolution of the processed images will be quadrupled, but the information content of algorithmically derived images do not contain more information than images which were originally recorded at the higher resolution.
The use case for this block is as a preprocessing step for object detection algorithms (ships, cars, planes etc) as the images become much crisper and contour outlines more well defined.
Note: The runtime of the algorithm is between 30 and 60 minutes per sqkm for Pléiades imagery.
