Detailed Description

Increase the image size by padding according to the zero-flux Neumann boundary condition.

A filter which extends the image size and fill the missing pixels according to a Neumann boundary condition where first, upwind derivatives on the boundary are zero. This is a useful condition in solving some classes of differential equations.

For example, invoking this filter on an image with a corner like:

* * * * *
 
* * * * *
 
1 2 3 4 5 (where * denotes pixels that lie
 
3 3 5 5 6 outside of the image boundary)
 
4 4 6 7 8

returns the following padded image:

1 1 2 3 4 5
 
1 1 2 3 4 5
 
1 1 2 3 4 5
 
3 3 3 5 5 6 (note the corner values)
 
4 4 4 6 7 8
