Modules  
AddC  
Adds a constant value to each pixel of an image. 

MulC  
Multiplies each pixel of an image by a constant value. 

MulCScale  
Multiplies each pixel of an image by a constant value then scales the result by the maximum value for the data bit width. 

SubC  
Subtracts a constant value from each pixel of an image. 

DivC  
Divides each pixel of an image by a constant value. 

AbsDiffC  
Determines absolute difference between each pixel of an image and a constant value. 

Add  
Pixel by pixel addition of two images. 

AddSquare  
Pixel by pixel addition of squared pixels from source image to floating point pixel values of destination image. 

AddProduct  
Pixel by pixel addition of product of pixels from two source images to floating point pixel values of destination image. 

AddWeighted  
Pixel by pixel addition of alpha weighted pixel values from a source image to floating point pixel values of destination image. 

Mul  
Pixel by pixel multiply of two images. 

MulScale  
Pixel by pixel multiplies each pixel of two images then scales the result by the maximum value for the data bit width.

Div  
Pixel by pixel division of two images. 

Div_Round  
Pixel by pixel division of two images using result rounding modes. 

Abs  
Absolute value of each pixel value in an image. 

AbsDiff
