CvInvokePerspectiveTransform Method (IInputArray, IOutputArray, IInputArray)

http://www.emgu.com

Transforms every element of src (by treating it as 2D or 3D vector) in the following way: (x, y, z) -> (x'/w, y'/w, z'/w) or (x, y) -> (x'/w, y'/w), where (x', y', z', w') = mat4x4 * (x, y, z, 1) or (x', y', w') = mat3x3 * (x, y, 1) and w = w' if w'!=0, inf otherwise
