sr.py       : Main algorithm file
0***.png    : Original image

-----------------------------------------------------------------------------
    Usage
-----------------------------------------------------------------------------

1) Change skimage.io.imread('0***.png') in main function.
2) Running `python3 sr.py' generates the following images.

    -- rec.png (reconstructed image by using our Fienup algorithm)
    -- rnd.png (reconstructed image by using randomized sign)
    -- jpg.png (JPEG)
