scOpponentFilter

 scOpponentFilter - spatial cielab spatial filter in opponent colors space

   filteredIm = scOpponentFilter(image, params)

 Spatial CIELAB calculation spatially filters the image data in
 opponent-colors space. This routine takes in input image in xyz or lms
 space, converts it to opponent color space, and applies the spatial
 filtering required by S-CIELAB. 

 The returned image, filteredIm, is converted into CIE-XYZ space.

 Example

  figure(1); imagescRGB(image);
