Arguments:

• size>=0[%],_order,_boundary_conditions,_nb_iter>=0    or
• axes,size>=0[%],_order,_boundary_conditions,_nb_iter>=0

Description:

Blur selected images by a box filter of specified size (fast recursive implementation).

order can be { 0:smooth | 1:1st-derivative | 2:2nd-derivative }.
boundary_conditions can be { 0:dirichlet | 1:neumann | 2:periodic | 3:mirror }.
When specified, argument axes is a sequence of { x | y | z | c }.
Specifying one axis multiple times apply also the blur multiple times.

Default values:

order=0, boundary_conditions=1 and nb_iter=1.

Examples of use:

• Example #1

• Example #2
