Joe, This is more of a question for the ITK discussion forum [1], but I'll give you a potential solution here.
The problem is that typedef itk::Image<unsigned char, 3> ImageType; declares a 3-dimensional scalar-valued image, not a 3-component (RGB) 2-dimensional image. To declare an RGB ITK image, try this: typedef itk::RGBPixel< unsigned char > RGBPixelType; typedef itk::Image< RGBPixelType, 3 > ImageType; I hope that helps.
