Detailed Description

High Quality double magnifier.

Author:
Bernard De Cuyper
Version:
1.1
Date:
24/03/2004
 
Purpose:        Define the concept of a very good double size magnifier. Better than bilinear and bicubic interpolations.
                This magnification take care of oblique edges. Based on rational operators.

Weakness:   Less blurring but it oscillates at strong edges, and it is more blocky than cubic spline.
                Not recommanded for segmentation, and really accurate edges. (Bernard comment)
