Image Operations > Arithmetics > Add Performs addition of the connected results (A+B).
Image Operations > Arithmetics > Subtract Performs subtraction of the connected results (A-B).
Image Operations > Arithmetics > Multiply Performs multiplication of the connected results (A*B).
Image Operations > Arithmetics > Divide Performs division of the connected results (A/B).
Image Operations > Arithmetics > Minimum Displays minimum of the connected results.
Image Operations > Arithmetics > Maximum Displays maximum of the connected results.
Image Operations > Arithmetics > Covariance Each pixel of the resulting image is calculated using two source images (A and B) as follows:
where E[X] is mean value over all pixels. The covariance is then calculated as mean pixel value (Covariance). Resulting image is always floating point image.
Image Operations > Arithmetics > Mask Image The connected color image is masked by the connected binary image.
Image Operations > Arithmetics > Remove Shading Applies the input B image to the input A image as the shading correction image. Formula for each pixel (multiplicative shading correction): output = ( mean(A) / mean(A / B) ) * (A / B).
A The image to be corrected

Image Operations > Constant > Add Adds an offset to the connected image.
Image Operations > Constant > Subtract Subtracts offset from the connected image.
Image Operations > Constant > Multiply Adds gain to the connected image.
Image Operations > Constant > Divide Divides the connected image by divisor.
Image Operations > Constant > Clip Clips the connected image based on the Min and Max values.
Image Operations > Constant > Constant Value Each pixel of this action result gets the specified value (Constant).
Image Operations > Functions > Abs Resulting image is an absolute value of the source.
Image Operations > Functions > Invert Intensity value of each pixel is calculated as the maximal value in the image minus the current value.
Image Operations > Functions > Exp Pixel exponentiation with the given base.
Image Operations > Functions > Inv Resulting image is an inversion of the source. Each pixel value is reciprocal (1/x) of the corresponding source pixel. Resulting image is always a floating point image.
Image Operations > Functions > Log Resulting image is a logarithm of the source.
Image Operations > Functions > Pow Pixel power with the given exponent.
Image Operations > Functions > Sign Computes Sign function for each pixel:
The image is converted to floating-point.
Image Operations > Logical > Greater Logical function greater than.
Image Operations > Logical > Greater or Equal Logical function greater than or equal to.
Image Operations > Logical > Equal Logical function equal to.
Image Operations > Logical > Not Equal Logical function not equal to.
Image Operations > Merge > Blend Merges Foreground channel a with Background b channel using Weight channel w.
Image Operations > Merge > Conditional Merges True channel a with False channel b using Condition channel c.
