Popis: Super-Resolution is the process of generating high-resolution (HR) images from a low-resolution (LR) ones. In learning-based SR algorithms, artificial neural networks (ANN) are used. This is achieved by training the network using HR and LR image pairs and use this network later to create new HR images from LR ones. Our work postulates that the scaling process is invariant across scales. Thus, a model trained at lower scales can be used to reconstruct higher resolution images when the ground truth is not available to train the model. We call this approach Scale Invariant Super-Resolution (SINV) We evaluated SINV using different datasets, and with different upscaling factors11The upscaling factor is the factor by which the image resolution is increased. and showed that it outperforms conventional approaches. We have applied SINV to processing InSAR images.
