Single Image Super Resolution (with GUI)

Image super resolution refers to the task of estimating a high-resolution image from its lower resolution version. In a more simple sense it requires us to generate pixel values for interpolating the given low resolution image to make it large. In this project I employ a deep learning approach to super resolve images to double or quadruple the original image. I used Keras with Tensorflow backend to implement the model in Python 3. The model I used is fairly simple and conists of layers of Convolutional and Deconvolutional with skip connections. A Mean Squared Error (MSE) loss is used to guide our model. I also designed a GUI with the model to make it to be used easily.

Super Resolution Example

The model is pre-trained with all weights included. So all you need to do is, clone this repository and run the sr_gui_browse.py. That's it.

GUI

The GUI provides a easy-to-use Interface for super resolution. The GUI has 2 options for Super Resolution, either to double or to quadruple the original input image. It also comes with an option of saving the Super Resolved image.
