Step1- First of all added the “global txt, txt2” to make variables global in clear(),TakeImages(),clear2() functions.
Step 2- (Important) Then changed the path directory to that of the project before running to ensure that all files will be available .
Step 3 - Then made certain GUI changes to take the data properly for registration purpose.
