Either two or three inputs. 1. image 2. mark file or 1. image 2. line disparity 3. sample disparity
REAL topo image.
Radius of circle within which points are collected to be used to interpolate over the central pixel (if it is zero). RADIUS should be greater than the MARK grid size.
For interpolation to be performed a minimum of MINPTS must be collected within the circle.
Number of passes to be performed through the image. If no points
are interpolated then iteration ceases.
