 ## Setup
 Supports Keras with Theano and Tensorflow backend. Due to recent report that Theano will no longer be updated, Tensorflow is the default backend for this project now.
 
+Requires Pillow, imageio, sklearn, scipy, keras 2.3.1, tensorflow 1.15.0
 ## Usage
 
 **Note**: The project is going to be reworked. Therefore please refer to [Framework-Updates.md](https://github.com/titu1994/Image-Super-Resolution/blob/master/Framework-Update.md) to see the changes which will affect performance.

     It can be calculated as

     When providing an unscaled input, MAXp = 255. Therefore 20 * log10(255)== 48.1308036087.
     However, since we are scaling our input, MAXp = 1. Therefore 20 * log10(1) = 0.
