Looking for a Reverse Mosaic Photo App

[112963]

Have several very blurry Mosiac Photos that I can't view any of the photos in it due to blurriness. May possibly be photoshoped to be blurry also but have multiple(30-40+) photos in each one that I would love to view. Is there an app out there to help me "undo" the photoshoped Mosiac Photos so that I can view all the pics in the Mosiacs? Please help.
