2014-06-26 10:18:08 -0600 | commented question | Problem with findContours and drawContours Well, I don't know why but I tested the same code with the same image on my friends computer, it works perfectly fine. The entire source code was what I posted in the question excluding the necessary headers, and the image board.jpg was in the opencv sample folder: sources\samples\cpp\board.jpg |

2014-06-25 12:28:06 -0600 | asked a question | Problem with findContours and drawContours Hi, I'm new to OpenCV, I was trying to run this simple code to find the contours of an image: But there was something strange about the output of the contours, it looks like this when I checked it: There are a lot of contours with an extremely huge size and all of their points are {x=??? y=???}. Is this normal output for findcontours function? Not only that, when I execute the program (release mode) to the end of the main function, I got two messages "myproject has triggered a breakpoint", after I pressed continue on both of them, I got "A heap has been corrupted" exception. While in debug mode, I got a Debug Assertion Failed: _CrtIsValidHeapPointer(pUserData). Everything else works fine if I comment the findContours and drawContours lines. How can I solve this problem? For more information, I was using VS2012 and OpenCV 2.49. |
