Hi.

I am writing a program which replaces detected face with replace image, the command line version works fine, but the gui just messes up, i dont know how.. I have compiled the command line one with Eclipse/MinGW/OpenCV2.0 and trying to compile GUI version with QT creator/OpenCV2.0/MinGW. the compile part work fine.. After select a input image and replace image, when i press the deanerize button the gui stops responding and gives "exited with code -1073741819 error". I tried the debugger and found nothing. mr. google said that i had an uninitialised value which i am trying to access and so it gives me error. I have written my code nearly 4-5 times from the working command line version but it just doesnt want to work. i have attached the code to work with please if you find anything even a small bit. it wil be very helpful. u can use any image for input/replace..

Thank you very much

Steps to Use:
1. Open Input Image
