  /** The Binary Operator class provides an abstract class interface for all 
      Operators that are computing a result image of two input images (e.g. 
      pixel-wise "+" or "-" operators.     
      
      \section OPLIST list of unary operators
      The ICLFilter package provides the complete filtering functions supported 
      by the ICL. Currently the following subpackages are included in the ICLFilter library:
      
      - <b>Arithmetic</b>: The Arithmetic Class contains a lot of arithmetic functions 
      (like add, mul,etc) working on images
      
      - <b>Canny</b>: The Canny Edge Detector, only available when having IPP. 
      
      - <b>Compare</b>: Compares two images, or one image with an constant pixelwise 
        and saves the binary result in an output image.
      
      - <b>Convolution</b>: The Convolution class provides functionality for any 
        kind of convolution filters.
      
      - <b>GeoTransforms</b>: Contains functions for mirroring and affine transformations.
      
      - <b>IntegralImg</b>: Class for creating integral images.
      
      - <b>LocalThreshold</b>:C.E.: **TODO** document this
      
      - <b>Logical</b>: The Logical Class contains a lot of logical functions (like 
        AND, OR, XOR, etc) working on images with integer Types
      
      - <b>LUT</b>: Class for applying table lookup transformation to Img8u images.
      
      - <b>Median</b>: Class that provides median filter abilities.
      
      - <b>Morphological</b>: Class that provides morphological operations.
      
      - <b>Proximity</b>: Class for computing proximity (similarity) measure between 
        an image and a template (another image).
      
      - <b>Skin</b>: This class implements a Skin color detection algorithm

      - <b>Threshold</b>: Class for thresholding operations

      - <b>Weighted Sum</b>: Accumulate weighted pixel values of all image channels

      - <b>Wiener</b>:  Class for Wiener Filter. Wiener filters remove additive noise 
        from degraded images, to restore a blurred image, only available when having IPP. 

      
      A detailed description of the provided functions in each package is included in
      the class description.
