This APP is a demo of the open source machine learning project TensorZoom-TF which use the Tensorflow to train an artificial neural network to scale up an image into a four time larger image with minimal distortion.
TensorZoom-TF is an open source project. Check the website to get more detail to get the source code and train your own super-resolution model. The model can be imported into the APP to test your result.
