Thanks. Another way of doing this is, if you can make engdemo.c or engdemo.cpp work, chances are people can then resolve more issues by themselves in trying to work with your example code which in turn will save you lots of time explaining them in the forum as well.
Adam, where is the laneMarkingAlgorithmWithVisualization.h and .lib in the zip ? And where is the \laneMarkingWithVisualization\distrib\ folder in the zip ? The reason why most people cannot run your exmaple files correctly is because it's too complicated and that's why things are misging here and there. Can you plz just provide a workable example for engdemo.c or engdemo.cpp ? I don't believe many people can even compile either one correctly and see results in Matlab, let alone your example files. Thanks.
