isoblur

Fast image processing for images in up to 4 dimensions (two spatial
dimensions, one time/depth dimension, one colour dimension). Provides most
traditional image processing tools (filtering, morphology, transformations,
etc.) as well as various functions for easily analysing image data using R. The
package wraps 'CImg', <http://cimg.eu>, a simple, modern C++ library for image
processing.

<dd>Standard deviation of the blur (positive)</dd>
<dt>neumann</dt>
<dd>If true, use Neumann boundary conditions, Dirichlet otherwise (default true, Neumann)</dd>
