i use pre-build opencv 2.4.9 i test the image show in opencv 2.4.9 it works,but for this source its have error?!
if this errors is that i use pre-build opencv?what to do what not to do
copy the xml file in current folder and my hardware corei5,Radeon ATI graphic

the error is a break in microsoft ,please help me.thanks very much
First-chance exception at 0x75C4B727 in opencv.exe: Microsoft C++ exception: cv::Exception at memory location 0x003CF678.
