I'm using Opencv248 (i didn't use cmake like for the older versions of OpenCV) Thanks in advence 2014-06-03 03:43:52 -0500 asked a question Eliminate too short or too long contours - Opencv2 Cookbook Hello to everyone, I've been following the tutorials of the OpenCV2 Cookbook, using Visual Stuido 2013. At some point I we have this code:  // Eliminate too short or too long contours int cmin = 1000; // minimum contour length int cmax = 10000; // maximum contour length std::vector>::iterator itc = contours.begin(); int i = 0; while( itc != contours.end()) { if (itc->size() < cmin || itc->size() > cmax) { itc = contours.erase(itc); } else ++itc; std::cout << i << " "; i++; }  When the compiler gets to: itc = contours.erase(itc);  It gives me this error: I've searched everywhere tried every possible way of spelling it doesn't work. And here is the driving crazy part, I tried the code on Visual Studio 2010 it worked perfectly fine. N.B.: I've tested the same code with a vector of vector of int in visual studio 2013 and it worked fine, so I guess the problem comes from VS2013 working with OpenCV. But I have no clue why.
