title: How to create a program that can read all the images in folder using Boost and OpenCV?
body: <p>What I want is simple: I need to open all images in a folder (I dont care for subfolders but it would be great to be able to search subfolders) and turn them into a vector of <code>IplImage*</code>s  so I can use Boost.Foreach to loop through each image. How can I achieve this?</p>
