My program run perfectly when I convert data from buffer into Mat (program to run video from external camera with frame grabber card). But after I try to develop a program to detect face, it has triggered a breakpoint.
My output window shows as follow:
/*
HEAP[my.exe]: Invalid address specified to RtlValidateHeap ( 03EC0000, 03F10ED0) // these codes are changing every debug.
This may be due to a corruption of the heap, which indicates a bug in my.exe or any of the DLLs it has loaded.
This may also due to the user pressing F12 while ......
