Error when compiling Example 2-1 on Learning OpenCV

Re: Error when compiling Example 2-1 on Learning OpenCV

Hi Travis
You have to supply 2 input arguments to the function
cvLoadImage. In addition to the name of file to be loaded, you have to specify
whether your image is color or gray.
So try to add
CV_LOAD_IMAGE_COLOR (or CV_LOAD_IMAGE_GRAYSCALE, or CV_LOAD_IMAGE_UNCHANGED)
as a second argument.
